Series RHPX Humidity and Temperature Transmitter
Passive Temperature Outputs, Indoor and Outdoor Enclosures
The Series RHPX Humidity and Temperature Transmitter accurately monitors the humidity and temperature for building control functions to maximize occupant comfort and minimize operating costs. Featuring capacitance polymer humidity sensors, models are available in 2% and 3% accuracies. An optional two-line alphanumeric LCD display is available. The high accuracy, long term stability and reliable operation in multiple enclosure styles make the Series RHPX an excellent choice for monitoring humidity and temperature in building energy management systems, commercial HVAC systems, clean rooms, museums and data centers. The Series RHPX can be optionally configured to supply absolute or relative humidity or dew point in addition to enthalpy.
