Overview
Details for RHP-2D2B
Duct mount 2% RH/temperature transmitter with 0-10 VDC RH output and 10K @ 25°C thermistor temperature output.
SERIES RHP HUMIDITY/TEMPERATURE TRANSMITTER
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.
