Testo’s 635-1 allows users to measure air moisture, material equilibrium moisture and pressure dew point inside compressed air systems.

The device is able to accept both Type K and NTC humidity probes (sold separately) and each of these clips directly into the tester’s ports at the bottom of the device. When using the type K probe temperature measurements can be taken from -200 to 1370°C and when using a NTC humidity probe the device has range of -40 to 150°C.

As well as these probes the Testo 635 is compatible with other probe types such as absolute pressure and type T.
