North American Wall Mount Humidity / Temperature Transmitter with 2% accuracy and universal current / voltage output for RH and 10K Type II thermistor Temperature Sensor
Series RHP-E/N Wall Mount Humidity/Temperature/Dew Point Transmitter
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.
