Series RHP-E/N Wall Mount Humidity/Temperature/Dew Point Transmitter

Brand: Dwyer Instruments, LLC
The Series RHP-E/N Wall Mount Humidity/Temperature/Dew Point Transmitter is the most versatile room transmitter on the market.

The stylish housing is well vented to provide air flow across the sensor to improve measurement accuracy. The humidity and the dew point are measured using a capacitive polymer sensor that completely recovers from 100% saturation.

The humidity and dew point can have either a current or voltage output, while the optional temperature output can be a current, voltage, RTD or thermistor.

For models with current or voltage for the temperature output, the temperature range is field selectable.
Features
  • Field selectable relative humidity or dew point output
  • Universal analog outputs
  • Integral or service tool LCD display options
  • Two housing designs to match North American and European aesthetics
