Details

The testo 635-2 temperature and humidity measuring instrument 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 the following measuring data:

  1. Relative humidity
  2. Material moisture
  3. Material compensation moisture
  4. Pressure dew point in compressed air systems
  5. HTC value
  6. Air temperature
  7. Surface temperature
  8. Core temperature
  9. Absolute pressure

Testo 635-2 is available with two sensor ports for pluggable sensors and up to 3 further temperature or moisture sensors which can be connected to the instrument via wireless along with an easy-to-read display.

Rugged, practical, easy to use
In addition to all the other measurements, the testo 635-2 temperature and humidity measuring meter also equips you to analyze levels of moisture at ceilings and walls by and calculate the dew point difference between the indoor air and the surface of the wall along with displaying min, max and mean values. Individually configured characteristic curves ensure that the material moisture content is displayed reliably
Both the meter and the menu guide are simple and comfortable to use with a backlit display which allows you to read the measurements even in poor lighting conditions. In addition, a strong protective case protects the meter effectively against any accidental knocks and bumps.

Saving, transferring and printing out data
as easy as pie with the testo 635-2 temperature and moisture meter
It also allows you to save measuring sites and allocate the measuring data to the relevant site. Create individual user profiles to perform parallel long-term and material moisture measurements. Save up to 10 000 readings – individual measurements and measurement series – to your meter. The USB cable in the scope of supply can be used to connect your moisture meter to your PC or laptop and the software allows you to log and archive your measuring data comfortably and easily. The optionally available testo fast printer also allows you to print out the measuring data on the spot.
