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.
