Series RHP Humidity/Temperature Transmitter

Brand: Dwyer Instruments, LLC

The Series RHP Temperature and Humidity Transmitter combine the voltage or current humidity transmitter output with a passive temperature thermistor or RTD output.

The polymer capacitance humidity sensor is not affected by condensation, fog, high humidity, or contaminants. The humidity sensors are available with 2%, 3% or 5% accuracies.

Duct mounted transmitters are available with an optional two-line alpha numeric LCD display.
