Room sensor for measuring relative humidity and temperature of air and other non-aggressive gases. Optionally available with LCD and operating elements. The reliable measurement (and control) of humidity prevents the formation of mold and contribures to a healthy and comfortable room climate. The accuracy of the humidity sensor is 2%. The device can be directly mounted on the wall, in a flush-mounted standard EU box or an optional surface-mounted frame.
