AIR HUMIDITY  TEMPERATURE DEW POINT METER
 

635-1 Hygrometer Air Humidity Temperature Dew Point
testo 635-1, humidity/temperature measuring instrument, with battery.
The instrument 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 printer.

Air Humidity Temperature Dew Point Meter

  • Printer for documenting measurement data on
    the site

  • Cyclical printing of readings once a minute,
    for example

  • Measures air moisture, material equilibrium moisture, pressure dewpoint

  • Radio probes for temperature and humidity

  • Protection class IP54

It is also possible, during cyclical printing, to print measurement data once every minute, for example. testo 635 immediately displays the dewpoint 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.
