Hand-held pocket-size instrument for measuring the ambient air humidity, the room temperature, the dew point and the wet-bulb temperature.

This instrument has been designed for quick measurements of the ambient air moisture and the temperature. The dew point (dew point temperature) as well as the wet-bulb temperature will also be determined automatically. The measuring instrument can be used in the building industry and in the field of building services engineering to establish the formation of condensate on surfaces, to prevent mold formation, for analyses and for other purposes.
