A Precision dew point hygrometer for industrial and process applications.

The Edgetech Instruments DewTrak ll dew/frost point and relative humidity transmitter is a compact, cost effective, primary method chilled mirror hygrometer for continuous measurement of moisture content of gases. Housed in a weatherproof enclosure, its modular design is available in a variety of mechanical configurations to accommodate a wide array of applications.

The DewTrak II provides high accuracy with long term stability and repeatability. It uses the chilled mirror dew/frost point temperature condensation principle to accurately determine the water vapor concentration in gas mixtures. The result is a highly precise yet durable moisture measurement device with very long life.

The DewTrak II is available with either the Edgetech Instruments D sensor or the higher performance DX sensor. Either may be mounted directly to the hygrometer’s chassis for ambient air monitoring or mounted remotely for insertion into glove boxes, HVAC ducts, environmental test chambers, circulation pipes, refrigerated storage rooms, engine test chambers and many other environments.
