The Testo 0636 9836 Precision Pressure Dewpoint Probe guarantees quick and accurate dew point measurement. The probe is the ideal probe for highly accurate measurements in the humidity range to -40°C tpd (e.g. in adsorption dryers to). By connecting the probe to the Testo 635-1 or 635-2 (available separately), the user has a portable, mains-independent measuring system. The large display on the measuring instrument enables the display of the relative humidity or the dew point with the temperature.
The 0636 9836 Precision Pressure Dewpoint 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 degrees C.The probe is connected to the compressed air system via a standard plug-in connector (G1/4" internal thread to ISO 228-1) or via a screw-on adapter for measurements at test points. If required other standard plug-in connectors with thread G 1/4" can be screwed into measuring chamber.
