Model HFG1 -Flow Mixer

The HFG1 allows users generate variable dew or frost point gas flows for the calibration of all types of hygrometers. It works by combining a dry gas supply with adjustable amounts of water vapor provided by an internal permeation humidifier. By adjusting the mixing ratio using the front panel mounted valves, output dew/frost points are generated for measurement using a reference hygrometer such as the 973 or 373.
