The sensor combination air temperature / relative humidity is used for the measurement of the air temperature and the relative humidity in connection with UNIKLIMA. According to standard, it is fastened on an aluminium cross beam in 2 m height with an optionally available radiation protection . The cross beam may be fastened to the 2 m - or 10 m - mast system available by the TOSS GmbH or to each mast supplied by the user.

The air temperature sensor and the humidity sensor can also be supplied individually in each case.

The air temperature sensor consists of a temperature-dependent silicon regulated current source, whereby there is no influence on the measuring signal / accuracy by the sensor line resistance / conduit length. Of course, on customer's request, we also supply the conventional PT100 .

The humidity sensor is structured as a planar multi-layer sensor and is equipped with a complex software temperature compensation.
