testo 635-1 – Professional moisture and temperature meter

Measures temperature, humidity and pressure dew point in compressed air systems. Readings from up to three temperature or temperature/humidity sensors can be displayed simultaneously. The sensors are so-called radio sensors, i.e. the measured values are sent wirelessly to the measuring instrument. Specific user profiles linked to function keys and to a menu guide make operation easy and intuitive.
The moisture content of materials can be shown directly on the display. Characteristic curves for different materials can be selected in the instrument. The Testo 635 also calculates the dew point distance between the ambient air and the surface temperature to analyze the risk of condensation on walls and ceilings, for example.

Precision sensors are available for measuring the pressure dew point in compressed air systems down to -60°C tpd. Testo’s patented moisture sensor has an outstanding performance in terms of hysteresis, long-term stability, temperature resistance and robustness.
