Humidity transmitters with temperature output for duct

RHT Duct is a relative humidity transmitter with temperature output installed in air ventilation duct. In addition to these measured values, RHT Duct calculates various parameters such as dew point, mixing ratio, enthalpy and absolute humidity. Illuminated display ensures easy readability also from a distance. The RHT has a screwless lid and an easily adjustable mounting flange that make the installation of the device easy.
