The Michell Instruments HG-1 Humidity Calibrator is a fully integrated system for the calibration of dew-point and relative humidity sensors from 2 to 90% relative humidity, -22 to 68°F (-30 to 20°C). The HG-1 is configured to operate as a stand alone calibrator or to operate from a dry compressed air supply enabling easy on-site calibrations. The calibrator features an integrated chilled mirror reference instrument to enable the operator to perform calibrations that are traceable to national standards. The chamber cover can be customised to suit the transmitters and sensors being calibrated.
