Humidity Transmitter / Dew Point Transmitter from Rotronic

Our humidity transmitter and dew point transmitter technology features digital processing of the internal signals so as to provide exceptional long-term stability and facilitate both maintenance and validation tasks. ROTRONIC offers a wide range of relative humidity transmitters and dew point transmitters. Depending on the transmitter model, the output signals can be configured to measure relative humidity, dew point, mixing ratio, enthalpy and temperature.
