•Probes available as an option mean you can measure air humidity, temperature, absolute pressure and dew point in compressed air
•Two plug-in probes and 3 radio probes can be attached
•Calculates dew point and dew point distance
•Display of min., max. and mean values

The testo 635-1 temperature and humidity measuring instrument enables you to measure the temperature, air humidity and dew point – in compressed air as well. State-of-the-art technology and a large selection of probes, which are available as an option, enable this wide variety of measuring possibilities.

Product Description
The testo 635-1 temperature and humidity measuring instrument is ideally equipped for checking the air humidity, temperature and dew point in living areas, in production, storage and server areas and in museums and cold stores. Measurements of the ambient absolute pressure and dew point in compressed air can be quickly and efficiently carried out with the testo 635-1.

Attachable probes, which are available as an option, mean the measuring instrument can record the following values:
•Air humidity
•Material moisture
•Pressure dew point in compressed air
•Air temperature
•Surface temperature
•Core temperature
•U-value
•Absolute pressure

The testo 635-1 temperature and humidity measuring instrument has two probe inputs for plug-in probes with cables. In addition, the testo 635-1 can receive readings by radio from up to three further temperature or humidity probes via wireless measurement data transfer and display them clearly.

You need the optional radio module as well as radio probes for radio measurement data transfer.
