North American Wall Mount Humidity / Temperature Transmitter with 2% accuracy and universal current / voltage output for RH and Temperature

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

Optional LCD Display

The Series RHP-E/N Wall Mount Humidity/Temperature/Dew Point Transmitteris 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 sensorthat completely recovers from 100% saturation. The humidity and dew point canhave either a current or voltage output, while the optional temperature output canbe a current, voltage, RTD or thermistor. For models with current or voltage for thetemperature output, the temperature range is field selectable.

• Air economizers
• Room comfort monitoring
• Greenhouse monitoring

• 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
