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 view the temperature to resistance lookup tables.

• Reduced installation cost with combined humidity and temperature
• Wide application environment from a large selection of temperature sensors and 2%, 3% and 5% accuracies
• Reduced system operating costs with radiation shield protecting the sensor from radiant heat
