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!

Time-efficient adjustment instrument

Connected, reliable measurement. Measurement values updated in seconds. Adjusting ventilation doesn’t get any easier than this. The Celsicom V600 is an adjuster’s dream.

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.

testo 162 loggers – part of testo Smart Connect

These data loggers are intended as a more permanent solution. They are powered by four AA batteries with an operating time of around one year and connect to a local Wi-Fi network. You can quickly read the current temperatures on the logger screens. All measurement data is also automatically sent to the testo Smart Connect cloud service. There you can easily configure the loggers, set limit values, analyze measurement data and send reports. If limit values are exceeded, you receive alarms by email. Connect to the testo Smart app for alerts via push notifications and even more smart features.

The testo 162 loggers are part of the testo Smart Connect measurement system, for monitoring sensitive indoor environments, and can also be combined with data loggers from the testo 160 or 164 series. The testo 162 T1 and testo 162 T2 data loggers meet the EN12830 quality mark and cover the monitoring of the most common temperature conditions in cold stores and freezers. Need for a larger measurement area? Then you should take a closer look at the testo 162 T3, which has a measuring range of -195 to +1 350 °C.

Celsicom logs

Compact logs, easy to move around and assemble. Powered by two AA batteries with approximately one year of operation. These loggers do not need a base station/gateway or local network. Each logger has its own connection via NB-IoT (Narrowband Internet of Things) on a frequency of the mobile phone network dedicated to data traffic.

The result: great coverage and virtually zero risk of interference. You can easily see the current temperature values on your mobile, tablet or computer. And you get unlimited cloud storage of measurement data in the Celsiview service for a low subscription cost. If you need to measure a wide range of temperatures or want two measurement channels, then choose the Celsicom TC602 with a measurement range of -200 to +1 372 °C.

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.

Stable and reliable radon values within one hour.

This allows you to quickly implement radon remediation measures.

Stefan Carlsson

CEO at Celsicom

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.

HA Bygg is literally laying the foundation for a new maternity hospital at Östra Sjukhuset in Gothenburg. A yellow smart concrete computer helps supervisor Fredrik Daun and his crew keep track of when castings have reached the right strength, saving a lot of valuable time.

The construction of the Eastern Hospital started after summer 2023 and is expected to last until 2028. A new maternity and neonatal building will be completed opposite Queen Silvia’s Children’s Hospital. As many as 12,500 deliveries per year will be possible in the new building.

The building will have a total of 11 floors. Nine floors above ground are dedicated to reception, maternity, neonatal and traditional care, as well as emergency rooms, overnight accommodation and administration.

4 000 cubic meters of concrete
There will be two levels of underground culverts. These culverts and the base plate of the house are cast by HA Bygg. It is an extensive job, to say the least. A total of 4,000 cubic meters of concrete is expected to be used to cast the 120-meter-long and 30-meter-wide base plate, walls and vaults. Some 40 people from HA Bygg will be employed until the end of this year.

To be able to see the status of castings at any time remotely, HA Bygg uses the Celsicom TC603 concrete computer. It is a compact and robust, connected and battery-powered concrete computer that uses two embedded thermocouple wires to continuously measure the concrete temperature. An internal sensor in the measuring box also records the ambient air temperature.

This saves us a lot of time!

Celsiview calculates strength
All measurements are automatically stored in the Celsiview cloud service. It also includes the concrete recipe used by HA Bygg. Using all this information, Celsiview can show the progress of the concrete’s curing and its current strength. In other words, supervisor Fredrik Daun and his colleagues do not need to make control measurements or calculate the concrete strength. All Fredrik has to do is log on to his mobile phone to instantly see the strength of the concrete at each measurement point.

Seeing concrete status in real time
– The Celsicom box is easy to use. Both in terms of entering recipes and keeping track of the concrete, says Fredrik Daun and elaborates:

– In the past, we have had to take intermediate measurements and make our own calculations based on experience of how the concrete develops under certain temperature conditions. Using this Celsicom box, we can see in real time how the concrete has behaved in terms of temperature and durability. And I can get an automatic email when the strength has reached 70 percent, so we can start demolishing the column and loading the concrete with the next floor.

Constant logistical challenges
The castings themselves are not very difficult to carry out. However, the logistics are difficult. Timing of deliveries is a constant challenge. Mainly because of the lack of space to lay materials before they are used in construction.

Therefore, it is nice for Fredrik and his colleagues to not have to worry about and keep an eye on the strength of the concrete. This is simply done for them by Celsicom TC603 and the Celsiview cloud service.

– This saves us a lot of time. In the long run, it probably means that we can save a lot of money as well,” concludes Fredrik Daun.

High humidity can delay even the most well-planned construction projects. Therefore, it is important to keep a close eye on the building climate to quickly see if the drying process is proceeding according to plan or if you may need to take extra measures to give the drying process a boost in the right direction. The Celsicom TH600 logger is a convenient, reliable solution for monitoring the building climate.

During house construction, many building materials with different moisture contents are used. To dry out the materials, fans and heaters are placed on the sites. It is then important to keep an eye on the construction climate to avoid costly delays which, in the worst case scenario, could result in the building not being completed on schedule.

Early warning signs

– The expulsion of moisture in building materials is often a slow process. You have to make sure that there is as little water as possible in the air, otherwise the material will not dry on time,” says Jens Åkervall of Nordtec.

If for some reason dehydration is not working properly, it is crucial to get warning signals about this as early as possible in the construction process.

– The heating may need to be increased and/or an additional fan installed to properly remove moisture from the building material.

Continuous monitoring

Sampling and measuring humidity is one way to assess the status of the building climate. However, if a control measurement shows a high humidity level and thus dehydration is too slow, it may be too late to remedy this, which then pushes back the timetable. Instead, continuous monitoring of the building climate is preferable.

– This is what the Celsicom TH600 makes so much easier and more efficient. It keeps you constantly updated on the construction climate so you can stay on schedule and avoid unnecessary delays,” says Jens Åkervall.

Current values and alarms

The Celsicom TH600 is a wireless and directly connected measurement box with internal sensors for measuring both temperature and humidity. Measurement ranges are -30 to +70 °C and up to 100 %RH. The compact and durable box is powered by two standard AA batteries that are cheap to replace – after about a year of operation. All measurement data is sent on a dedicated, reliable frequency on Telia’s mobile network to the Celsiview cloud service.

– You can view current temperature and humidity values at any time, for example on your mobile phone. And if any of your limits are exceeded, you will receive an automatic text message or email and can quickly take action.

Valuable documentation

Getting started with the Celsicom Easy Connect TH600 is easy. All you have to do is remove the snap-on lid of the box and scan a QR code to activate the temperature and humidity measurement. You can create an account in the Celsiview cloud service in a few minutes.

Ocab has been around since 1964 and is a nationwide company with broad expertise in remediation, moisture and the built environment. Since its inception, the business concept has been to help customers save value in the event of damage caused mainly by fire and water. Ocab is constantly exploring new technologies and methods. For some time now, around 100 measuring boxes from the Celsicom Easy Connect monitoring system have been tested in the Stockholm area.

The opportunities that come with the product are fully in line with Ocab’s strategic focus on digitalization and sustainability.

– We see great potential in the new meters. They can contribute to savings in terms of time, costs and the environment, which is of course very interesting for us and our clients,” says Thomas Karhu, production manager in dehumidification at Ocab in Stockholm.

What are the main clients and most common assignments?
– Insurance companies are our biggest customers, with fire and water damage being the most common.

Ocab’s mission is to ‘save the world’. What does it mean?
– Basically, it means that through quick and effective action we can save economic values and possessions of high personal value that cannot be replaced. But there is an additional perspective: cleaning up and dehumidifying instead of disposing or demolishing is saving existing resources, which is both sustainable and cost-effective. Preserving rather than throwing away and demolishing is in everyone’s interest and we are actively working on new and improved methods that make this increasingly possible. Specifically, we can dry the structure of a water-damaged floor at a fraction of the cost of demolishing it.

It is as the name says. They are super simple.

Thomas Karhu

Production manager in dehumidification

What are the most common types of moisture damage?
– The most common moisture damage today occurs in kitchens where there are usually more machines installed than in the past. In businesses, coffee machines and water machines are often the ones that start leaking. In private homes, water damage is caused by dishwashers, ice machines for freezers and poorly drained sink pipes. Waterproofing damage in bathrooms is also a major problem.

How to prevent water damage?
– Above all, it is about complying with the laws that exist. If you do this, there will be less water damage. Specifically, the sink cabinets should be made watertight by inserting a watertight base into the cabinets. This makes it easy to see if water is accumulating inside the cabinet and prevents the water from running under the cabinet and damaging the structure. Furthermore, there should be no pipe connections in walls and floor structures, only solid pipes.

What is your background in the water damage industry?
– I have been working on this since 1996. I am a trained builder and have then further educated myself in techniques for moisture measurement in new constructions and existing environments.

What makes the job interesting and exciting?
– It’s a varied job and there is always something new to develop. It never gets boring!

What are the technological developments in the sector?
– It has been rather stagnant. In recent years, there has been more environmental thinking and the production of more energy-efficient dehumidifiers. In the case of monitoring drying processes, remote sensing technology has been available but has been less effective and complicated to install.

What made you discover the Celsicom boxes?
– Stefan Carlson from Celsicom came here and showed me one of the new meters, which made me very interested. The boxes are a great fit for us and our industry. They are also easy for our technicians to install. No weirdness at all, just as it should be.

What are the 100 measurement boxes you have bought used for?
– We use them exclusively for dehumidification of water damage. We have installed all measurement boxes and are now fully testing this. If the outcome is good, we will definitely continue to use them.

What is the best thing about Celsicom Easy Connect boxes?
– It is just as the name says. They are super simple. It was just a matter of scanning and we had the measurement boxes uploaded to the server. The only thing you need to do beyond scanning the meter is to enter the damage address for each meter.

How do measurement boxes make your job easier?
– During dehumidification in a water damage, we normally need to perform so-called intermediate measurements to know the status of the drying process. We can now save that trip and time as the status is quickly checked via mobile phone. The customer gets quick feedback by sending them a screenshot. We can also check that a dehumidifier is up and running and working properly by simply following the curves of the drying process – directly on the mobile phone.

Does Celsicom Easy Connect enable you to get more business?
– Yes, I think so. If we see that the result of using the Celsicom boxes is what we want, it should free up many hours for our humidity technicians, which in turn means that we can take on more jobs with the same number of technicians.

Finally, is there any technical solution you would like to see in the future?
– Being able to “invite” customers to see the status of their items would be a good feature. It would also be an advantage to be able to control and switch off the electricity on our dehumidifiers via Celsicom Easy Connect.

– A dehumidifier that is running may give wrong values when a final measurement is made and therefore the dehumidifier should be switched off three days before the measurement. If it can be switched off remotely, we would further reduce the need for transportation, which in turn is an important aspect of our sustainability work.

Simply and safely without interference. This is how Ida Alexandersson and Staffan Johansson review the yellow loggers from the Celsicom Easy Connect measurement system used to remotely monitor the casting of an underground train station.

During work on Stage Centralen, an underground section of the West Link in central Gothenburg, we had a chat with the project team on site. On behalf of the Swedish Transport Administration, NCC was responsible for the construction of an underground station called Station Centralen. 35 Celsicom TC603 loggers were placed at various locations in the huge concrete shell, continuously delivering valuable data from the casting of concrete slabs, outer and inner walls and roofs.

Monitoring cooling and concrete status
The yellow concrete loggers enable efficient and safe remote measurement. This is what Staffan Johansson and Ida Alexandersson, supervisor and deputy supervisor respectively at NCC, said when they reflected on the work on the concrete shell for the 700 meter long and 50 meter wide train station. During the pour, 1,700 cubic meters of concrete were used to pour a 940 square meter concrete slab. Some of the data loggers monitored the temperature of the water cooling the concrete, to ensure the correct curing process.

Two other concrete computers recorded the temperature evolution of the concrete during the curing process through two measuring wires each embedded in the concrete.

– Everything has worked very well. There were no disturbances at all and the concrete computers logged every ten minutes, which meant we got very reliable strength curves,” says Ida.

The measurement system has been easy to use from the very beginning, she says.

We could start using them right away!

Using 35 yellow so-called concrete computers, NCC monitored the concrete strength during the construction of the underground Station Centralen.

– The day we got them here, we could start using them right away. Just peel off a small sticker and they were connected directly to the login(in the Celsiview cloud service) that we have – and started measuring immediately. It was very smooth, no problems at all.

Staffan agrees. The yellow temperature loggers have made the job much easier, he says.

– We have had full control over the temperature of the concrete. All such updated information is available at all times on your computer or mobile phone. This meant that we could, for example, go in and immediately say: Okay, now we have the right strength for the structure – let’s demolish the mold.

For NCC, the Celsicom loggers provide security during work on the underground station, the train tunnel and other parts of Stage Central.

– I think the most important thing is that you can quickly check if there is an interruption. Nowadays you spend more time inside than outside. Then it feels good to be able to easily go to our site and see if all measuring points are running,” says Staffan Johansson.

Ida Alexandersson adds:

– You can more easily keep track of what is happening. If a test lead is pulled out, you will see exactly what time this happened.

Safe concrete pours
The 35 existing data loggers will be in operation until NCC finishes the concrete work for this stage of the West Link.
