The Testo 635-2 (0563 6352) Compact Pro Thermo-Hygrometer offers the possibility of testing and analyzing air humidity, material moisture, U-value and the dewpoint in compressed air systems. In addition to measurement with classical probes, a wireless measurement over up to 20 m distance is also possible with the testo 635-2. This eliminates damage to the cable or difficulties in handling. The wireless probes are available for the measurement parameters temperature and humidity. Up to three wireless probes can be recorded and displayed by the testo 635-2. The optional plug-in radio module can be retrofitted at any time.

The testo 635-2 stands out thanks to its intuitive operation and clear menu structure. For example, for measurements at different measurement sites, the testo 635-2 provides the advantage that the measurement values can be allocated to the respective measurement site. For long-term measurements and material moisture measurements, the instrument can be switched between different user profiles. The 635-2 has extended instrument functions such as an instrument store, PC software, direct display of material humidity and the possibility of connecting a U-value probe.

Rugged, Practical, and Easy to Use

The testo 635-2 Compact Pro Thermo-Hygrometer can display min/max/avg values, and calculate the dew point difference between the indoor air and the surface of the wall. This allows you to analyze moisture levels at ceilings and walls. Individually configured characteristic curves ensure the material moisture content is displayed reliably.

Both the meter and the menu guide are simple and comfortable to use, while the backlit display allows you to read the measurements in poor lighting.
