Humidity Dew point meter.

635-2 Hygrometer Humidity Temperature Dew Point Measurement.
testo 635-2, humidity - temperature measuring instrument with readings memory, PC software and USB data transmission cable, with battery. The instrument for measuring air moisture, material equilibrium moisture and pressure dew point in compressed air systems.
Moisture characteristics can be recorded in the instrument memory and analyzed and displayed in graphics or tables. Up to 3 temperature or humidity probes can be displayed in the testo 635-2 meter; data transmission is by radio i.e. wireless.

635-2 Hygrometer

Model  Description 
0560 6351  635-1 Compact Pro Thermohygrometer
0563 6352  635-2 Compact Pro Hygrometer w/memory and software

Selectable user profiles, i.e. allocation of specific function buttons and menu-guide to an application enable intuitive operation. Material moisture can be displayed immediately on account of the special probe.
Characteristics for different materials can be stored in ComSoft and transmitted to the instrument. testo 635 immediately displays the dewpoint difference between ambient air and the wall surface in the analysis of oisture on walls and ceilings.
Precision probes up to -60°C tpd are available to check pressure dewpoint in compressed air systems.
The humidity sensor developed by Testo has proven itself worldwide and has outstanding features in terms of precision, long-term stability, temperature resistance and robustness.
