Product Description

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.

Rugged, practical, easy to use

In addition to all the other measurements, the testo 635-2 temperature and moisture meter can also display min, max and mean values and calculate the dew point difference between the indoor air and the surface of the wall. This allows you to analyze levels of moisture at ceilings and walls. 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. A backlit display allows you to read the measurements in the dark or poor lighting and 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

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.

And just when you thought it couldn’t get any easier: the optionally available testo fast printer allows you to print out the measuring data on the spot. There’s testo for you.
