Microprocessor multifunction thermo-hygrometer WCM-1 Thermo-hygrometer WCM-1 is an electronic microprocessor based device used to measure 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.

The sensors used to measure air humidity and temperature are contained in a ϕ30x150mm probe which is connected to the device with a 1.5m long cable. TP-1 Electrode has a magnetic handle, which facilitates measuring temperature of steel surfaces.

To calibrate and test the WCM-1 the manufacturer uses a high quality humidity generator DGW-2 which was certified by the National Institute of Weights and Measures in Warsaw.
