1. APPLICATION

Thermo-Hygrometer PCE-WM 1 is an electronic microprocessor based device for
measuring relative air humidity (%RH), temperature (°C), absolute humidity (g/m3) and dew
point temperature (°C). It is equipped with TP-1 Electrode which enables the user to obtain
temperature readings for various surfaces (e.g. steel constructions). Absolute humidity and
dew point temperature are calculated by the microprocessor, which performs linearization
and mathematical computations.
The device is widely used in industry and laboratories, it is extremely user friendly. It is
supplied together with other standard equipment in a shock proof case.
