Testo 0636 9835 Pressure dewpoint probe for measurements in compressed air systems, probe length 300 mm, -22 to 122°F / -30 to +50°C tpd, 0 to +100 %RH, fixed cable

Standard Pressure Dewpoint Probe

The probe was developed in cooperation with a world market leader in the compressed air engineering sector. The standard probe 0636.9835 is sufficient for most measurements in compressed-air piping (e.g. refrigeration dryers in the range from 0 to 2 °C tpd).

The pressure dew point tpd is the temperature at which compressed air reaches the saturation state (100% RH). This value is an important criteria for the perfect running of the compressed air plant. 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. The sensor is positioned in the flow of compressed air being measured, for the duration of the measurement. The probes can be used, without a measuring chamber, in accordance with the Instruction Manual for the testo x35 instruments. By connecting the probe to testo x35 the user has a portable, mains independent measuring system. The large display enables the display of the relative humidity or the dew point with the temperature.
