The two pressure dew point probes guarantee quick
and accurate dew point measurement.
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 t
pd
).
The
precision probe 0636.9836
is the ideal probe for
highly accurate measurements in the remaining
humidity range (e.g. in adsorption dryers to
-50 °C t
pd).
The pressure dew point t
pd
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.
