Thermohygrometer with Battery and Calibration Protocol

This measuring instrument needs a probe for being commissioned. Testo 635-1, humidity/temperature measuring instrument, with battery and calibration protocol. Overview: The testo 635-1 for measuring air moisture, material equilibrium moisture and pressure dewpoint in compressed air systems. Up to 3 temperature or humidity probes can be displayed; data transmission is radio-controlled, i.e. wireless. Measurement data can be transmitted by infrared to the Testo printer. It is also possible, during cyclical printing, to print measurement data once every minute, for example. testo 635-1 immediately displays the dewpoint difference between ambient air and the wall surface when analysing moisture on walls and ceilings. There are precision probes up to -60°C tpd available to inspect pressure dewpoint in compressed air systems. The humidity sensor developed by Testo has proven itself world-wide and has outstanding features in terms of precision, long-term stability, temperature resistance and robustness. What's Included: Testo 635-1 temperature and humidity measuring instrument, including calibration protocol and batteries. Key Features: Probes available as an option mean you can measure air humidity, temperature, absolute pressure and dew point in compressed air Measures air moisture, material equilibrium moisture, pressure dewpoint Calculates dew point and dew point distance Cyclical printing of readings once a minute, for example
