• testo 635-2 - Temperature and moisture meter

Part # 0563 6352

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.

Delivery Scope

testo 635-2 temperature and moisture meter, PC software, USB data cable, calibration protocol, batteries. PLEASE NOTE: a sensor (not in scope of supply) is required to operate the meter.
