The testo 635-2 temperature and moisture meter is excellently equipped for carrying out a variety of measurements in the field of air conditioning. A wide selection of optionally available sensors and probes can be connected to the meter to provide you with the following measuring data:
- Relative humidity
- Material moisture
- Material compensation moisture
- Pressure dew point in compressed air systems
- HTC value
- Air temperature
- Surface temperature
- Core temperature
- Absolute pressure
Two sensor ports for pluggable sensors; up to 3 further temperature or moisture sensors which can be connected via wireless with the temperature and moisture meter. The results are presented on the easy-to-read display. Your meter can be upgraded with an optionally available plug-in type wireless module which can transmit a wireless signal over a distance of up to 20 meters.
