The Series RHPX Humidity and Temperature Transmitter provides precise monitoring of humidity and temperature for building control applications, helping optimize occupant comfort while reducing operating costs.
The Series RHPX Humidity and Temperature Transmitter provides precise monitoring of humidity and temperature for building control applications, helping optimize occupant comfort while reducing operating costs.
The Series RHPX Humidity and Temperature Transmitter delivers accurate humidity and temperature measurement for building control applications, supporting improved occupant comfort and reduced operating costs. Using capacitance polymer humidity sensors, models are available with 2% or 3% accuracy. An optional two-line alphanumeric LCD display provides clear local readout. With high accuracy, long-term stability, and reliable performance across multiple enclosure styles, the Series RHPX is well suited for building energy management systems, commercial HVAC applications, clean rooms, museums, and data centers. Optional configurations allow output of absolute or relative humidity, dew point, and enthalpy in addition to temperature.
