The calibratable humidity and temperature sensor measures the relative humidity and ⁄ or the temperature of the air

It converts the measured humidity and temperature into a standard signal of 0 - 10 V or 4...20 mA, and is available with or without an optional display (for displaying actual humidity and actual temperature), in an elegant enclosure made of plastic, with snap-on lid, base with 4-hole attachment for installation on vertically or horizontally installed in-wall flush boxes, with predetermined breaking point for on-wall cable entry, or in an enclosure made of stainless steel (top and bottom part are of stainless steel, the lid is screwed on), vandal-proof version e.g. for schools, military barracks, and public buildings.

It is used in non-aggressive, dust-free environments, in refrigeration, air conditioning and clean room technology, in interior rooms, such as living rooms, offices, hotels, engineering rooms, meeting and conference facilities. The measuring transducers are designed for exact detection of temperature and humidity. A digital, long-term stable sensor is used as a measuring element for humidity and temperature measurement. Fine adjustment by the user is possible.
