SERIES RHP HUMIDITY/TEMPERATURE TRANSMITTER

Passive Temperature Outputs, Sintered Filter Options

The Series RHP Temperature and Humidity Transmitter combine the voltage or current humidity transmitter output with a passive temperature thermistor or RTD output. Featuring polymer capacitance humidity sensors, models are available in 2%, 3% or 5% accuracies. Duct mounted transmitters are available with an optional two-line alpha numeric LCD display.

For models with resistive thermistors or RTD outputs, please click here for temperature to resistance lookup tables.

NIST CALIBRATION available in Product Configurator.

Product Applications

Air economizers
Outdoor temperature and relative humidity reference
Pool room humidity monitoring

2%, 3%, or 5% accuracy models
Optional LCD display on duct mount models
Radiation shield option for outdoor installation in direct sunlight
