Precision pressure dewpoint probe - for measurements in compressed air systems

0636 9836
Precision pressure dew point probe
  • Fast and accurate determination of the pressure dew point
  • Robust humidity sensor with long-term stability 
  • Connection to the compressed air system via standard plug-in connection
  • Measuring range: -40 to +50 °C tpd
  • Check compressed air lines reliably: the precision pressure dew point probe with measuring chamber is ideally suited for fast and accurate determination of the pressure dew point and for high-precision measurements in the trace humidity range.
    The pressure dew point is an important criterion for ensuring that compressed air systems work perfectly. Use the precision pressure dew point probe with measuring chamber (combined with the appropriate measuring instrument) to determine the pressure dew point quickly and accurately.

    The probe runs through an elaborate adjustment process: in addition to standard adjustment, it is subject to fine adjustment at the factory at a pressure dew point of -40 °C.

    Connection to the compressed air system is via a standard plug-in connection (G1/4” internal thread as per ISO 228-1) or via a test connection screw fitting (for measurements on vehicles). If necessary, other standard plug-in connections with a G 1/4” thread can also be screwed into the measuring chamber. The probe can also be used for indoor air humidity and temperature measurement without a measuring chamber.
