635-1 Hygrometer Air
Humidity Temperature Dew Point
testo 635-1, humidity/temperature measuring instrument, with battery.
The instrument for measuring air moisture, material equilibrium moisture
and pressure dewpoint in compressed air systems. Up to 3 temperature or
humidity probes can be displayed; data transmission is radio-controlled,
i.e. wireless. Measurement data can be transmitted by infrared to the
printer.

It is also possible, during
cyclical printing, to print measurement data once every minute, for
example. testo 635 immediately displays the dewpoint difference between
ambient air and the wall surface when analyzing moisture on walls and
ceilings.
There are precision probes up to -60°C tpd available to inspect pressure
dewpoint in compressed air systems. The humidity sensor developed by
Testo has proven itself world-wide and has outstanding features in terms
of precision, long-term stability, temperature resistance and
robustness.
