Dwyer RHP-2N4A Humidity/Temperature Transmitter with 10K type III thermistor temperature sensor, 2% accuracy

$277.10

Dwyer RHP-2N44

Well-vented to provide airflow across the sensor to improve measurement accuracy, this wall-mount transmitter measures humidity, temperature, and dew point. By using a capacitive polymer sensor that completely recovers from 100% saturation, humidity and the dew point are measured accurately.

Features

  • Field selectable relative humidity or dew point output
  • Universal analog outputs

Applications

  • Air economizers
  • Room comfort monitoring
  • Greenhouse monitoring
