- relative humidity
- material moisture
- pressure dew point in compressed air systems
- air temperature
- surface temperature
- core temperature
- U-value
- absolute pressure

The temperature measuring device testo 925 is used for temperature measurement in heating engineering, sanitary engineering and refrigeration and air conditioning technology. A temperature sensor type K can be connected to the testo 925:
