The testo 635-1 is ideal for checking temperature, air humidity and dew point in work areas, production areas, server rooms as well as in museums and cold stores. Absolute pressure and dew point measurements in compressed air can be carried out quickly and efficiently with the testo 635-1.
Measuring features of the temperature and humidity meter testo 635-1
By connecting the appropriate probes you can easily measure:
- Air humidity
- Material moisture
- Dew point pressure in compressed air
- Air temperature
- Surface temperature
- Core temperature
- U-Value
- Absolute pressure
The testo 635-1 temperature and humidity meter has a connection port for a cable probe. In addition, the testo 635-1 can connect up to three other wireless temperature or humidity probes.
In addition to the measured values, the testo 635-1 temperature and humidity measuring instrument also displays Max./Min. and average values.
The testo 635-1 temperature and humidity measuring instrument is really easy to use with the measurement guidance menu stored in the device. The testo 635-1 with integrated display light makes it comfortable to use in all lighting conditions. The testo 635-1's robust housing protects the measuring instrument from impacts.
