Our loggers in the Celsicom Easy Connect product series use NB-IoT technology and send all measurement data via their own reliable frequency in the mobile network. Temporary disruptions may occur, but the loggers will reconnect as soon as they can. In exceptional cases, loggers, like any other technology, may lose connectivity. If you see in the Celsiview cloud service that a Celsicom logger has not been connected for a certain period of time, it may be time to restart or change the battery.

Here’s how to fix connectivity problems:

1. open the Celsicom logger. Check that everything seems OK. For example, that the batteries are not leaking, that the SIM card is correctly inserted in its holder and that the circuit board is not water damaged.

On new Celsicom loggers, there is a restart button (labeled RST) between the batteries and the SIM card. When you press the button, you hear a short beep. The logger will now restart and try to connect to the mobile network. When you hear three beeps and see a green flashing light, the logger is connected. The faster the light flashes, the better the signal strength.

Do you have an older Celsicom logger without a restart button (RST)? Then remove the batteries, wait for at least 60 seconds and then put the batteries back in. You will hear a short beep, which means the logger is restarting and looking for the mobile network. Three beeps and a green flashing light then mean that the logger is connected.

4. Once you have successfully connected the Celsicom logger , it is ready to start measuring immediately. Enter Celsiview to get a visual confirmation that the logger is connected and active.

If you have any questions or problems connecting your Celsicom logger following the steps above, please let us know.

Setting up ventilation is important to ensure a good indoor climate and to keep operating costs down. But, as many of us know, it is often a time-consuming process, especially when it comes to large systems where several technicians often have to work together to measure flow and pressure several times in different places in the buildings to achieve optimal ventilation adjustment.

Thanks to the Celsicom V600, these problems are a thing of the past. In fact, with the help of the meter, a ventilation technician can perform really big adjustment jobs all by himself.

Adjustment of ventilation with Celsicom V600

All you need to set airflows in a system is our new tuning instrument, an optional airflow meter and a mobile phone or tablet. Here is our step-by-step guide to setting up ventilation with the Celsicom V600:

• Remove the sliding cover of the Celsicom V600 and scan the QR code inside with a mobile/tablet
• Create an account on the Celsiview cloud service webpage that appears on the screen
• Add the Celsicom V600 and choose the instrument for your measurement
• Identify the weakest point of the ventilation system, i.e. your reference device
• Enter the K-factor and projected value for reference actuators and other actuators
• Connect the calibration instrument to the reference device and the measurement is underway.
• Celsicom V600 guides you through the entire proportional adjustment process
• The mobile/tablet displays the current adjustment values for each sensor
• If a pressure change occurs in the system, new values are calculated – in seconds!
• Finally, raise or lower the reference actuator to 100% (as designed) and the values of the other actuators will be automatically adjusted

“No need to go back and check measurements”

This is how ventilation adjustment works with Celsicom V600. One person who has discovered the advantages of the new adjustment instrument is ventilation technician Tor Halvorsen at VXPro AB. Tor has used the instrument for several large adjustment jobs and believes that it facilitates and improves his job in several respects.

– I don’t have to spend time doing my own calculations, nor do I have to go back and check the reference device. In the past, it often took at least three trips to get all the values right. Now I get it right straight away,” says Tor, adding that the Celsicom instrument makes him more efficient.

– It saves at least a third of the time. Up to half in some cases. Depending on the accessibility and complexity of the systems.

Impressively accurate alignment

In addition to the time savings, the Celsicom V600 and Celsiview allow Tor to perform large adjustments with impressive precision. He often exceeds the requirement of six percent accuracy in the adjustment between the sensors by far.

– “I often get down to three percent accuracy, which benefits everyone. The tenants get a comfortable indoor climate and the property owners lower energy consumption,” says Tor Halvorsen, who sees how the smart measuring instrument allows him to “do more in less time”.

– This is a great solution that gives me more capacity every day of the week!

Discover other Celsicom meter boxes

The Celsicom product family also offers measurement boxes for accurate measurement and analysis of other quantities such as temperature, humidity and differential pressure to ensure safe and optimal environments in many different industries.

Companies operating in sectors such as construction, real estate, moisture damage management and the food industry benefit greatly from Celsicom’s flexible and precise measurement boxes. Whether you need to ensure indoor air quality, monitor workplace conditions or meet critical environmental parameters, Celsicom can help you do so with the highest accuracy and reliability.

Summer and sun, nice and carefree days – if you have a safe monitoring system in place and keep track of food temperatures in your cold and freezer rooms. So that you don’t suddenly find yourself with unusable raw materials and inedible food in the middle of summer.

A power cut, a door ajar, too many goods in the same space… there are several risky scenarios for your cold stores that are difficult to anticipate, prevent and detect in time. Especially in summer. Fewer staff and holiday replacements mean that supervision is not kept up with or is forgotten. Instead of keeping an eye on temperatures, it’s about servicing the rush of customers.

Avoid unnecessary additional costs

High outdoor temperatures in summer make it warmer indoors, which in turn can lead to higher temperatures in food storage areas. If you are not observant and quickly detect excessive temperatures, you may be forced to discard large quantities of produce and food. This is an immediate, unexpected and unnecessary additional cost, and it can be disruptive to business. In other words, you may have obvious problems delivering raw materials or offering food to customers in the near future before you have time to get home and restock.

Fortunately, there are various solutions for easy and reliable monitoring of cold stores. Peace of mind when food storage facilities are unmanned or when you and your colleagues simply don’t have the time to check the space from time to time. Choose the measurement solution that suits you best: data loggers from the testo Smart Connect or Celsicom monitoring systems.

Simple and flexible monitoring with alarms

It’s easy to get started with logs from both systems. You don’t need to install any software, just open a browser, create an account and make a few settings – then the loggers are ready to start measuring. You can check current values remotely whenever you want.

An important detail: the loggers automatically send alarms via SMS or email if any cooling or freezing temperature approaches a critical limit. The alarm function can be linked to one or more of your employees and an external refrigeration company that is on call.

Ventilation technician Tor Halvorsen uses Celsicom V600 reference sound level meters for ventilation adjustment.

Med över 20 års erfarenhet i branschen vet ventilationstekniker Tor Halvorsen vikten av pålitlig mätutrustning för effektiva injusteringar. Sedan drygt ett år använder han Celsicom V600. Resultaten har varit otvetydiga: mindre tidsåtgång och precisare luftflöden, jämnare drifter och betydande energibesparingar.

Tor Halvorsen and his colleague Patrik Pålsson at VXPro AB specialize in ventilation adjustments in all types of properties. Everything from homes belonging to small and large housing associations to commercial premises and offices in properties of all sizes.
– When we work for housing associations, it can be from twenty to several hundred apartments with three to seven measuring points per apartment. For example, in a residential area with 300 apartments, there may be an average of around 1,500 air diffusers. In addition, there are public spaces such as laundry rooms and community halls. So it’s important to work smart with ventilation adjustment,” says Tor Halvorsen.

Traditional tuning – time consuming and outdated values

Traditional tuning means that the reference sensor is measured repeatedly during the tuning of the other sensors. This is necessary to see the current ratio (the relationship between the current value and the target value) to adjust against. The ventilation technician then has to go back to the reference device often, usually three times – sometimes up to six or seven times, to check it. After a while, it becomes uneconomical to go back to the reference device after each throttling. If control measurements are not taken, the result is that the current quota is not always available.
The solution to avoid time-consuming control measurements and minimize adjustment errors is real-time reading of the current ratio. With traditional tuning, real-time reading can only be achieved by a technician continuously measuring the reference actuator and communicating the new ratio via radio or telephone to the colleague throttling the actuators.

Celsiview cloud service – real-time reading with Celsicom V600 for fast and more precise ventilation adjustment.

Averaging is the key

Many measurement solutions for real-time readings consist of reference dosimeters connected via radio or Bluetooth (with limited range) and a base station and modem. The Celsicom V600 consists of a single unit: a compact, battery-powered reference densitometer.
After the meter automatically connects to the mobile network, the ventilation technician continues his work in the web-based Celsiview cloud service on a mobile or tablet. The screen displays the current values of the reference actuator and guides the technician through the adjustment of all actuators.
– Thanks to the Celsicom V600 averaging, I can see immediately if the values are within the right range. I can easily see fluctuations in pressure and use the average instead. This means I can often get the difference down to two or three percent, which is more accurate than the normal method error of six percent,” says Tor.

“Small and flexible measurement solution”

Tor previously used Celsivent, the predecessor of the Celsicom V600. He was quickly impressed by the new model:
– The V600 is a small and handy measurement solution. Apart from the meter itself, all you need are batteries and measuring hoses, an optional airflow or pressure gauge, and your regular mobile phone or tablet. It starts up and connects quickly. After a few minutes, you are ready to start measuring.

Tor also appreciates a number of small but important details that make his job easier. These include the magnetic bracket and the measuring hook that allow Tor to easily and safely connect the V600 to supply air and exhaust air devices.
– I also like the fact that the battery status is clearly displayed on the tablet, so I don’t have any unpleasant surprises. The operating time is also really good. I can often measure for several days without having to change the batteries in the V600, which is powered by standard AA lithium batteries.

Emergency jobs cleared quickly

Tor and his colleague Patrik recently got a clear proof of the benefits of Celsicom V600 during a job on the island of Öckerö outside Gothenburg. At short notice, they responded urgently and made adjustments in two properties with a total of 18 apartments.
– We expected to spend eight hours, but finished in five. And that’s despite the fact that the installation wasn’t finished when we arrived. We even had to help the electricians with the control technology to get the fans going,” says Tor and adds:
– “It was good for us to once again get confirmation of how well the Celsicom meter works. The adjustment itself took about three to four hours, which is also three times faster than traditional ventilation adjustment!
No wonder that Celsicom V600 has become an obvious work tool for Halvorsen and Pålsson at VXPro AB.
– Everyone I have recommended it to is happy. It is an invaluable tool for anyone working with ventilation adjustments.

There are many places in a church that can be exposed to moisture, causing damage to walls and ceilings, furnishings and decorations, textiles and books. An increasing number of parishes and pastorates have started to systematically log humidity and temperature – often remotely – to avoid costly moisture damage and minimize heating costs. In Örebro parish, for example, there are clear benefits from remote monitoring of the indoor climate in churches.

Mold and other microorganisms are common in churches. Cleaning up microbial growth takes a lot of time and money. To counteract this, the Church of Sweden has been working actively for many years to ensure a good indoor climate in church buildings. As part of this work, a comprehensive handbook on the facts and detection of moisture in different environments has been produced.

Increased need for metrology

“Moisture, or water, is the single most important factor in determining whether a church building is affected by mold. Keeping moisture and water loads in check prevents damage,” the manual states. At the same time, it notes that mold problems do not seem to be going away but rather the opposite: climate change, with increasing rainfall and warmer climates, is predicted to give churches more work in controlling and managing moisture levels.

The handbook is aimed at those who both plan and carry out the operation, maintenance and supervision of churches in parishes and pastorates. It is divided into the following seven inspection rounds: the crawl space, soil and drainage, the façade, the attic, the roof, the interior of the building and in connection with surveying.

Not everything can be seen or smelled…

There are many sources of moisture, such as rainfall and soil moisture, leakage and humidity. Discoloration, stains and flaking plaster and paint can indicate moisture damage. Similarly, an unusual, pungent smell can reveal the presence of mold. But in a remarkable number of cases, mold growth is fairly anonymous. The mould cannot be seen or smelled until the growth is well advanced. If microbial growth is suspected, the Church of Sweden therefore recommends that adequate measuring equipment be used to measure and monitor the presence of temperature and relative humidity (RH) in several places in the church.

So what causes moisture problems in churches and where should measurements be taken? Open doors (e.g. during summers), leaks and exhaled air from visitors during services are some sources of warm air meeting cool surfaces (such as church walls) and causing condensation. Surfaces made of organic material or soiled by carbon particles from burning candles are a good breeding ground for microbial growth.

Moisture alarm from microclimate measurement

In a church there are many microclimates. These are small, confined areas where temperature, air circulation and humidity may differ from the climate in other parts of the space. These microclimates, which may have elevated moisture levels, are found under pews and pulpits, behind altarpieces and fixtures placed/attached to an exterior wall. One microclimate that’s important to keep an eye on is the storage of mess kit, alba, smock and other garments. Textiles are sensitive and should ideally not be exposed to relative humidity higher than 50% RH. Many churches use the mobile-connected Celsicom TH600 to measure moisture in these and other spaces. If the moisture value is exceeded, the user receives an automatic alarm via SMS or email. By also using the Celsicom TC602 measurement box, you can perform additional measurements and correlate these with measurement data from the TH600 in the Celsiview cloud service. It gives you the RF value of a surface in real time, allowing you to quickly see if the surface is so cold and damp that there is a high risk of mold growth.

Moisture content in exposed wooden structures

Water leaks and warm air entering roof and floor structures can result in damp environments and a breeding ground for mold. With the help of the Celsicom MM611B connected measuring box, churches have the opportunity to quickly and easily measure the moisture ratio continuously. They monitor the water content of exposed wooden structures such as roof and floor joists and can detect at an early stage any damage caused, for example, by water ingress.

Temperature measurement that saves costs

Energy saving is a priority for many businesses. Churches are no exception. In many cases, intermittent heating is used. That is, church buildings are basically only heated for services, weddings, baptisms and other ceremonies. The Celsicom TH600 is a perfect measurement solution in this context as well. The measuring box tells you how long it takes to heat the church. This can help churches ensure perfectly timed, comfortable indoor climates for different services while reducing heating costs.

Move and measure wherever you want

The Celsicom family of measurement boxes are all small and compact, reliable and battery-powered. It only takes a few minutes to activate a box to start measuring. The boxes can be placed almost anywhere and are easy to move when a new measurement need arises.

Radon is a radioactive gas produced when the element radium decays in the ground. So-called radon daughters then bud off and attach to dust that we breathe in and get into our lungs. Radon provides the highest exposure to ionizing radiation (high energy electromagnetic radiation).

There may be radon in the ground under and around a building. It is the most common source of radon. Otherwise, radon can be measured in building materials such as concrete, bricks and aerated concrete and in domestic water. Especially in rock drilled wells or cold springs. High radon levels in municipal water are unusual.

Reference levels and risks

The reference level for radon in Sweden is 200 becquerels per cubic meter (Bq/m3). At higher radon levels, property managers should act quickly and take measures to reduce the levels as much as possible.

Long-term exposure to elevated radon levels increases the risk of developing lung cancer. Smokers are particularly at risk of being affected. An estimated 500 lung cancer cases per year can probably be attributed to radon in homes, according to the Swedish Radiation Safety Authority.

How to detect radon

Radon cannot be smelled or seen. Measurement is the only way to detect and map the presence of radon in a building. You should measure continuously between October 1 and April 30, i.e. during the heating season. The measurement should be carried out for at least two months – around the clock in different weather conditions to capture variations in temperature, wind conditions, ventilation systems, air circulation and so on. The longer the measurement period, the more accurate the readings.

It is good practice to carry out radon measurements at regular intervals. In particular, you should measure radon if it has been 10 years since the last measurement and if the building has been rebuilt or renovated.

Four different measurements of radon

The Swedish Radiation Safety Authority has produced method descriptions for radon measurement in homes and workplaces. These descriptions emphasize that all spaces should be used as usual during the measurement. For example, the heating and ventilation settings are just as usual. There are essentially four different types of measurements, all performed over different periods of time: long-term measurement, follow-up measurement, short-term measurement and instantaneous measurement. These methods are described here in brief.

Long-term measurement is the overall method for radon measurement in homes and workplaces. It is done with tracer film canisters deployed to capture radon daughters (see explanation above) over a measurement period of at least two months. The results of the measurement are then sent to a lab for analysis.

Follow-up measurements are made in cases where long-term measurements are believed to have overestimated the radon level in, for example, a workplace. As a complement, a follow-up measurement is then carried out for at least seven days and five working days in order to also obtain measurement data during evenings and nights (when many people usually reduce or turn off ventilation, which can lead to an increase in radon levels) in order to obtain a more accurate picture of radon levels.

Short-term measurement is an option in cases where a long-term measurement cannot be carried out for some reason. Can be selected to measure radon levels in workplaces with temporary work periods. The measurement shall last for at least five working days. Short-term measurement can also be used to provide an indication of whether an ongoing radon remediation project is progressing according to plan.

Instantaneous measurement is a direct measurement of radon levels during working hours. The measurement is made over a short period of time, usually a few hours. The measurement uncertainty for instantaneous measurement is greater than for the other measurement methods.

“Stable and reliable radon values within one hour”

For several years, Celsicom has developed and launched a range of smart measurement boxes for different measurement sizes. One of these is the Celsicom THR600 radon meter (read more below).

– It is a great complement to the long-term measurement of radon. The box is easy to set up. And you have stable and reliable radon values within an hour. This allows you to quickly implement radon remediation measures,” says Stefan Carlsson, CEO of Celsicom.

He adds that the Celsicom box is also a very valuable tool during remediation.

– You can follow the process hour by hour and see if your actions are effective. Simply ensure that the remediation is proceeding according to plan and the radon levels are gradually decreasing.

The Church of Sweden Örebro Pastorate actively monitors the indoor climate in a large number of churches and office buildings. As part of this work, building technician Johan Asplund uses Celsicom loggers.

The pastorate aims to reduce heating costs by 15% – without sacrificing optimal climates for people, furnishings and equipment. This means that it should be +20 C° in offices, +18 C° in sacristy rooms and +13 C° in church rooms.

“Better control of metrics”
It is important that these temperature levels are maintained. Altar linens and vestments are sensitive to low temperatures (and high humidity, RH). The same applies to paintings, wooden sculptures and metal objects.
– With the help of the Celsicom loggers, we can have better control of different metrics,” says Johan Asplund.

Churches are temporarily heated
To keep energy costs down, some churches are not fully heated at all times. Instead, the heat is raised during church services and other ceremonies. The Celsicom logs give Asplund answers to how long before the heating needs to be turned up so that the right temperature is reached at the right time, and how the RH value in the church room is affected by time-limited heating.

Johan and his colleagues receive automatic alerts via SMS or email if limits are exceeded.

– This makes the logs particularly useful because the churches are so geographically dispersed. If I see that the temperature is about to drop a lot in a room, I can go there quickly and check if there is a problem with the power supply or if a radiator has failed.

Construction of the West Link is taking place under and above ground around Gothenburg. At the Kallebäck exit west of the E6, concrete engineer Frida Mesch and her colleagues at NCC are busy casting in and outside the southern tunnel mouth of the rail link. They use around 30 concrete computers to keep track of the strength at all times.

There is a flurry of activity when we meet Frida Mesch in Kallebäck. Excavators are used to prepare the ground and rebar is laid down for future pours. Frida is a fairly new concrete engineer. It was mostly a coincidence that I chose this particular career. After high school, Frida trained as a flight instructor. Largely to get flying hours and then be able to further train as a pilot. But after a while she got tired of it and was tipped off by a staffing agency about a position at a company that manufactures concrete pipes.

– I really liked it there, but after a while I felt that I wanted to develop myself further. When I was on maternity leave and was actually looking for courses for my partner, I found out about a course at Yrkesakademin to become a concrete engineer,” Frida says and continues:

– I was already working with concrete and thought it was a fun material. So I became interested in learning more. I have always been insatiable on learning new things.

Thesis on the concrete computer

At the end of her training, Frida had an internship at NCC. It was then that she discovered the Celsicom remote monitoring system and the Celsicom TC603 concrete computer.

– Someone in our project had heard about Celsicom and thought we should use it for our castings. But none of my colleagues knew exactly how the monitoring system worked, so it was my job to find out,” says Frida.

This resulted in Frida doing her thesis on the concrete computer from Celsicom and the associated cloud service Celsiview where all measurement data is saved and documented during both ongoing and completed casting. In order to clarify various issues during the thesis, Frida received valuable help from Fredrik Andersson and Stefan Carlsson at Celsicom AB.

“Everything is very simple”

A clear advantage of Celsicom’s concrete computer emerged during the thesis work, says Frida:

– Simplicity. Everything from settings to use is very simple. When you look at other concrete computers, you’re a bit intimidated by how technically complicated they look.

Her evaluation of the standard recipes in Celsiview showed that there is not much difference in the strength calculation if you have a slightly different recipe but it still contains the same cement as a base, Frida says and elaborates:

– You don’t need to make strength calculations yourself. The system does that for you. And the strength calculation is always based on empirical measurements of conditions in and around the concrete, whether I calculate it myself or let the computer do the job. In the end, whatever the method of calculation, you still have to drill out a core and test it to know exactly.

This and other knowledge of the Celsicom monitoring system is of great use to Frida in her daily work at NCC. She and her colleagues use no fewer than 32 concrete computers to pour floor slabs, walls and roofs for the area at the southern tunnel mouth of the West Link.

Clients receive detailed documentation

Frida praises, among other things, the possibility to get the current status of an ongoing casting.

– For example, if I cast something the other day and want to check the strength, I can go into the mobile and get a message very quickly. It’s incredibly convenient.

The concrete computers are also used to measure the temperature of the cooling water to and from the concrete. The temperature difference in these water flows must not be more than four degrees. If this happens, it can cause stresses in the concrete, which can lead to cracks.

– Another great advantage of the Celsiview cloud service in particular is that the client receives very detailed and good information about the castings when we hand over our final documentation. They can enjoy professional overviews with clear and attractive charts.

Challenging and fun material

There’s no mistaking that Frida Mesch likes working on the West Link. When she started her internship a few years ago, no concrete had been poured in the Kallebäck area.

– It’s been great to see it all come together.

She describes concrete as a challenging material that can behave in different ways. It’s important to “keep your wits about you”, as Frida puts it, otherwise it’s easy to make mistakes and, for example, to end up with a cast that you have to repair.

– The big challenge is to get the perfect cast without a single air bubble. It is very difficult but at the same time a fun challenge.

– “I’m really keen to build my own house. If I had the money for it, I would start right away,” says Frida Mesch with a laugh.

Briefly about the West Link Project

The West Link is an approximately eight-kilometer double-track railway for commuter and regional trains in the Gothenburg area. More than six kilometers of railway tracks will run in a tunnel under central Gothenburg. In the north, the tracks go underground in the Gullbergsvass neighborhood (near Skansen Lejonet) to come up in the Kallebäck area south of Gothenburg. Three new stations will be built along the new underground route: Station Centralen, Station Haga and Station Korsvägen. Construction of the West Link started in 2018 and is originally scheduled for completion in 2030.

Since 2016, energy engineer Billy Axelsson has been using data loggers from the Celsicom measurement system to remotely monitor various indoor climates in Kil municipality’s buildings. The loggers enable more efficient work and reduce energy consumption and the risk of costly breakdowns.

Billy Axelsson works at the property unit with responsibility for energy and ventilation. It is a small job considering that the municipality operates on about 60,000 square meters in about 50 buildings. These buildings house commercial kitchens, schools, nurseries, leisure facilities, care homes – and a range of other businesses.

An important part of the real estate unit’s work consists of remote monitoring of various climate parameters in different environments, in order to analyze important measurements on a daily basis and schedule measures or, if necessary, respond immediately. Measured variables such as temperature and humidity are monitored with data loggers from the first generation of the Celsicom measurement system (the loggers are connected to base stations) and data loggers from the second generation of the same system (these loggers have their own connection via the Narrow Band Internet of Things on their own frequency in the mobile phone network). In total, there are 107 measurement sites in 27 buildings.

Celsicom – an important backup
The fact that Celsicom was chosen eight years ago was mostly a coincidence.

– We have some comprehensive systems for monitoring and controlling heating and ventilation in our buildings. But I felt the need to have some kind of backup to be able to have continuous control and get alerts. “At one point I bought a thermal imaging camera from Nordtec and was a bit curious about what other fun things you had,” says Billy.

That’s when he discovered and chose to test Celsicom. Since day one, the remote monitoring system has greatly facilitated the work of the real estate unit. Above all, the ease of getting started and using the Celsicom logs is appreciated. The automatic limit alerts via SMS or email are also praised. And the fact that the purchase of each logger – including the subscription cost for storage and analysis in the Celsiview cloud service – is a modest investment.

Automatically alerts in good time
The real estate unit has found a variety of applications for the Celsicom loggers. Here are some examples of what they are used for.

– If a chiller breaks down or starts leaking refrigerant, the chiller can continue to run while the temperature starts to rise. This can quickly be seen from diagrams in Celsiview.

– Another great advantage is the possibility of receiving an alarm if, for example, a large meat fridge breaks down. Then you have to act quickly to avoid having to throw away goods worth SEK 100,000 the next day.

Celsicom loggers are also used in schools to ensure a good indoor climate in classrooms, to monitor temperature and humidity in music rooms and to prevent damage to stringed instruments. The remote monitoring also covers four pellet plants. There, Celsicom loggers simply alert you if pellet levels are approaching a critical level and it’s time to refill.

Preventing an expensive mishap
– I have also made a little invention of my own with one of the latest Celsicom loggers that has moisture ratio sensors (Celsicom MM611B). I’ve connected it to a screw in a wooden plank lying on the floor of a basement where we have very little supervision. And last winter there was a water leak from the heating system! I was alerted within an hour that the moisture content was too high in the wooden plank and was able to go there to quickly fix the flood and leak. It could have been really expensive if I hadn’t had that monitoring,” says Billy.

Celsicom also eliminates time spent traveling around checking conditions in different properties.

– Instead, I always have updated readings via the Celsiview cloud service on the home page of my computer. I can quickly see if something seems strange and can easily see how things are developing, and then decide whether I or someone else needs to go to the scene.

Good information and data
Celsiview is also a good tool for sharing information and providing input for various improvements. For example, staff in commercial kitchens can log in and have a ‘watch’ function to check temperatures in cold rooms and freezers in real time for their own control.

One of the property unit’s major challenges in the future is to make operations more efficient by, for example, reducing electricity and district heating. It’s about reducing energy use as much as possible without sacrificing a comfortable indoor climate. In this respect too, deployed Celsicom loggers are valuable tools.

– It is very easy to quickly see on your mobile phone, tablet or computer where the temperature is a bit too high and can be turned down to reduce heating costs. “In an electrically heated school that is in storage, I have Celsicom connected to the heating system to be able to keep the temperature as low as possible without it freezing in the winter,” says Billy Axelsson and notes:

– We save a lot of money by having sensors monitoring the radiator groups.

Our compact, robust Celsicom meter boxes give you full control of moisture on construction sites or after water damage in a property. You can view updated measurement data directly on your phone at any time.

Remote monitoring of building moisture

The Celsicom TH601A and TH601B measurement boxes provide you with convenient and reliable monitoring of moisture remaining in wood materials and concrete slabs on construction sites. By logging in to the Celsiview cloud service on your mobile phone, tablet or computer, you can quickly access current measurements.

The TH601A is equipped with a 0.4 meter external cable sensor while the TH601B has a 2.0 meter external cable sensor. Both are robust measurement boxes that can measure moisture in harsh environments, such as a concrete slab using the RF method, for a long time. A specially adjusted sensor can be purchased for the 75-95 %RH range to achieve maximum accuracy.

Remote monitoring of dehumidification

The measuring boxes are also ideal for accurately monitoring the moisture situation after water damage in different types of properties. Depending on the extent of the water damage, the moisture monitoring boxes are installed in the concrete structures. You can then easily follow the dehumidification process remotely on your phone, tablet or computer.

By setting alarm limits, you will automatically receive a text message or email when dehumidification is complete.
