    Your advantages
  1. Probes available as an option mean you can measure air humidity, temperature, absolute pressure, and dew point in compressed air
  2. Measures air moisture, material equilibrium moisture, pressure dew point
  3. Calculates dew point and dew point distance
  4. Cyclical printing of readings once a minute, for example
    5. 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.

    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.

                                                            Localising mould

                                                            Damp ceilings and walls may be a result of structural damage. In most cases, however, it is a sign of improper ventilation. Once the mould appears inside a house, the tenant assumes that moisture has come in from outside. Numerous disputes have erupted because of the issue of who is liable for the mould damage. However, it is difficult to find out who or what has caused the mould: the tenant or faulty structural design?

                                                            Testo 635-1 is ideal for measuring moisture in ceilings and walls. Using the optional attachment temperature/moisture probe and optional surface temperature probe, the testo 635 automatically calculates the dew point distance. It provides initial information about whether mould is being caused by condensation, or from moisture ingress due to structural damage or faulty insulation.

                                                            Monitoring production and storage conditions

                                                            Our temperature/humidity measuring instruments are used around the world in production, storage and server rooms, museums, archives, cold storage warehouses, containers and sales counters.

                                                            Manufacturers, carriers, or dealers of sensitive products must ensure that specified temperature or humidity values are observed during production and storage. The testo 635 offers the option of performing spot measurements in relevant places.

                                                            The temperature/humidity measuring instrument testo 635-2 offers the user a wide range of humidity/moisture probes. It provides the option of measuring humidity, material moisture and U-value (for the thermal assessment of structural components). In addition to the standard probes, up to three radio probes can be connected to the device in parallel. Measurement results can be analysed, stored and documented using the supplied PC software.
