The humidity and temperature are precisely monitored by the Series RHPX, Model RHPX-3SDA0-00 Humidity and Temperature Transmitter for building management functions to enhance occupant comfort and decrease operating expenses. Models using capacitance polymer humidity sensors come in 2% and 3% accuracy options. There is a two-line alphanumeric LCD display available as an alternative. The Series RHPX is a great option for temperature and humidity monitoring in commercial HVAC systems, clean rooms, data centers, museums, and building energy management systems due to its high precision, long-term stability, and dependable performance in a variety of enclosure types. In addition to enthalpy, the Series RHPX can be set to offer absolute or relative humidity as well as the dew point.
