Electronic sensor for the measurement of relative air humidity and temperature. The measuring cell is based on the resistive electrolytic measurement principle for the humidity and a NTC element for the temperature detection. The sensor armature is made of stainless steel.  

The robust HIS sensor is suitable for the use in clean rooms as well as in air ducts with high air speeds. It measures accurately and free of any hysteresis. This makes it especially good for a precise and quick control of the climatic parameters.
