Series RHP Humidity/Temperature Transmitter
Brand: Dwyer Instruments, LLCThe 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.
Features- 2%, 3%, or 5% Accuracy Models
- Optional LCD Display on Duct Mount Models
- Radiation Shield Option for Outdoor Installation in direct sunlight
