Use the testo 440 dP airflow and indoor climate meter in combination with high-quality sensors (and also testo SmartProbes) to measure and save all ventilation and indoor climate parameters (sensors ordered separately). Up to 3 sensors can be connected simultaneously: a Bluetooth sensor, a cable sensor and a temperature sensor with thermocouple connector type K. Thanks to automatic sensor detection and clearly structured measurement menus, the instrument is very easy to use and will make your daily measurement tasks much easier.

The testo 440 dP already has an integrated differential pressure sensor. It allows you to perform measurements on filters and fans, as well as with pitot tubes (prandtl tubes) and with K-factor (measuring hook ordered separately).

Measure with just a few clicks
Measuringshould be quick and easy – the testo 440 airflow and indoor climate meter automatically recognizes all connected sensors. This means that you never have to manually reset any measurement parameters when switching to another sensor. Clearly structured measurement menus for duct/vent volume flow, k-factor, turbulence degree, cooling/heating load, moisture damage risk indication and logging function. These menus allow you to complete measurement tasks faster, more efficiently and more reliably. Reports can be exported as Excel files via the USB interface or printed on site.

Wireless and compact – more applications, less equipment
Highly versatile: with a universal handle that can be connected to any transducer, you can handle more applications with less equipment, while taking up more space in your toolbox.
The Bluetooth handle can transmit readings up to 20 meters, eliminating cable clutter and freeing up space in your toolbox. As a practical option, a cable handle is also available. This is a big advantage if Bluetooth signals are not allowed.

Practical data management
The multi-instrument can store up to a maximum of 7,500 measurement blocks which can be read out via a USB port and further processed as a CSV file on your computer (e.g. with Excel). With the Testo BLUETOOTH/IRDA printer (ordered separately), you can print a report with your measurement data directly on site.

Intelligent calibration concept for maximum accuracy
You can rely on accurate measurement results when using our digital sensors, as the measurement uncertainty in the instrument is now eliminated. You only need to send in the sensor part for calibration and continue using the multi-instrument itself.

Advantages and features of the testo 440 airflow and indoor climate meter

Accurate and reliable in channels and ducts

• There is a wide range of sensors to choose from: hot wire and vane sensors for measurements in ducts, large Ø 100 mm vane sensors for measurements on wall and ceiling diffusers.
• Quick calculation of the airflow: in the measurement menu, simply enter the dimensions and shape of the duct. The airflow is shown directly on the instrument display in either l/s or m3/h.
• You will also discover how easy it is to measure on really big donors. That’s because the telescope on wire rope and flywheel sensors can be further extended with the telescope accessory – allowing you to extend the sensor to a total length of 2 meters.
• Take measurements at high altitude without using a ladder. Connect the extendable telescopic sensor at a 90° angle to the sensor and, if necessary, also the telescopic accessory (both ordered separately).
• Use the wing wheels in combination with Testo measuring nozzles over air diffusers and ventilation grilles.
• Practical Bluetooth interface: use the airflow sensors without the hassle of cables. Simply press the button on the handle to, for example, start and stop a calculation of the time average at a particular measurement point.
• Use the handy magnets to attach the multi-instrument to a metal surface (e.g. a ventilation duct).

Long-term measurement of indoor air quality

The robust metal enclosure makes the testo 176 T3 temperature logger suitable for use in harsh environments such as the UK. You can measure and log the temperature at up to four points simultaneously. It is possible to connect four TE type K, type T or type J thermocouple sensors with thermocouple contacts. You can choose thermocouple sensors from our wide range of sensors (see tab “Sensors”).

The advantage of thermocouple sensors is that they react very quickly and cover a large measurement range. For example, you can log especially low temperatures (as low as -195°C) using a type K temperature sensor – depending on the model selected – or you can perform high temperature measurements (up to +1000°C). This allows you to measure in super freezers and also monitor high temperature industrial processes.

The temperature data logger’s memory can store up to 2 million measurements and is therefore suitable for long-term measurements, eliminating the need to read out the measurement data too often. The data logger has a battery life of up to 8 years, which also makes it a practical instrument for long-term measurements.

Technical features and practical benefits

The temperature data logger testo 176 T3 has a metal enclosure, which is a great advantage for e.g.. temperature monitoring in harsh environments. It can also withstand hard shocks and impacts and is fully dust- and water-proof according to protection class IP65.

The datalogger logs the temperature in the oven and afterwards the temperature progression can be analyzed second by second. The special vacuum-insulated glass container protects the data logger’s electronics from both radiant and contact heat. After 1.5 hours in an ambient temperature of +200 °C, the temperature in the container increases to a maximum of +70 °C. Thanks to this, the data logger can pass through thermal processes in, for example, paint, bakery or conveyor belt ovens. The temperature sensors connected to the data logger are placed outside the enclosure to measure process temperatures on parts or in the air. There is a wide range of customized temperature sensors to choose from.
