    Product Description

    testo 635-1 - Humidity measuring instrument

    Description

    The testo 635-1 is for measuring air moisture, material equilibrium moisture, and pressure dew point in compressed air systems. Up to 3 temperature or humidity probes can be displayed; data transmission is radio-controlled, or 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.
    The testo 635-1 immediately displays the dew point difference between ambient air and the wall surface, when analyzing 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.

    Delivery Scope

    testo 635-1 temperature and humidity measuring instrument, including calibration protocol and batteries
    Caution: The instrument can only be commissioned with a probe. These are available separately.
    Your advantages
    • 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 dew point
    • Calculates dew point and dew point distance
    • Cyclical printing of readings once a minute, for example
    The testo 635-1 temperature and humidity measuring instrument enables you to measure the temperature, air humidity, and dew point – in compressed air as well. State of the art technology and a large selection of probes, which are available optionally, allow for a wide variety of measuring possibilities.
