The testo 635-1 is for measuring air moisture, material equilibrium moisture, and pressure dew point in compressed air systems. Up to 3 temperature or humidity probes can be displayed; data transmission is radio-controlled, or wireless. Measurement data can be transmitted by infrared to the Testo printer. It is also possible, during cyclical printing, to print measurement data once every minute, for example.
The testo 635-1 immediately displays the dew point difference between ambient air and the wall surface, when analyzing moisture on walls and ceilings.
There are precision probes up to -60°C tpd available to inspect pressure dewpoint in compressed air systems. The humidity sensor developed by Testo has proven itself world-wide and has outstanding features in terms of precision, long-term stability, temperature resistance and robustness.

Features:

Probes available as an option mean you can measure air humidity, temperature, absolute pressure, and dew point in compressed air
Measures air moisture, material equilibrium moisture, pressure dew point
Calculates dew point and dew point distance
Cyclical printing of readings once a minute, for example
