RHP-3N4B

RHP-3N4B is a series RHP North American style wall mount humidity/temperature dew point transmitter. This is 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. 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. Typical applications include air economizers, room comfort monitoring, greenhouse monitoring.
