Precision pressure dewpoint probe

0636 9841
Precision pressure dew point probe
  • Fast and accurate determination of the pressure dew point 
  • High-precision trace humidity measurement
  • Pressure dew point measuring range: -40 to +50 °C tpd
  • The ideal probe for fast and accurate determination of the pressure dew point. In addition, it is suitable for high-precision measurements in the trace humidity range and also enables fine adjustment to any pressure dew point in the -40 to +25 °C tpd range at +25 °C (single-point adjustment).
    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.

    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.

    Note: You need a plug-in head cable (0430 0143) for this probe.
