HD2 Series Analog Humidity Sensors provide an ideal solution for measuring relative humidity in a wide range of conditions. All models are equipped with a solid state capacitive humidity sensor that is easy to replace in the field. They are also equipped with a solid state temperature sensor that provides high accuracy measurements.
HD2 is an all-in-one device combining humidity and temperature sensing. Intended for duct mount applications, the device ensures a building’s optimum temperature and humidity levels, resulting in greater energy efficiency. Each device is an active sensor that converts a humidity or temperature measurement into 4-20mA, 0 to 5 Vdc or 0 to 10 Vdc analog output.
