The GE Telaire Vaporstat 9002 Dew Point Sensor is the first commercial infrared dew point transmitter that directly measures dew point.
The Vaporstat 9002 Dew Point Sensor from GE Telaire is a new generation, low-cost moisture sensing device that directly measures water vapor rather than relative humidity. A relative humidity measurement reflects the amount of moisture air can hold at a certain temperature. If the temperature changes, the relative humidity will change. In contrast, the water vapor sensor measures the absolute amount of water vapor in the air and is unaffected by temperature. The GE Telaire Vaporstat 9002 Dew Point Sensor provides a similar performance to a chilled mirror but is a fraction of the cost and requires considerably less adjustment and maintenance.
