Because it uses a primary method chilled mirror sensor to detect the dewpoint, the DewTrak II by Edgetech Instruments doesn’t need periotic recalibration to remain accurate and repeatable over the long term as other hygrometer types do. Periodic recalibration can be expensive and disruptive. The DewTrak II eliminates this troublesome maintenance headache.

The DewTrak II is available with either the Edgetech Instruments D sensor or the high performance DX sensor to accurately and rapidly determine the water vapor concentration in air and gases. Both sensors are now available with an effective membrane filter element surrounding the sensor mirror. Porosity of the membrane may be chosen to suit the application. The membrane filter eliminates maintenance by eliminating mirror contamination by particles in the measured air or gas stream. The sensor does not require cleaning under continuous use in dirty environments.

Either sensor may be mounted directly to the hygrometer’s chassis for ambient air monitoring or they may be mounted remotely for insertion into glove boxes, HVAC ducts, environmental test chambers, circulation pipes, refrigerated storage rooms, engine test chambers and many other environments.

The DewTrak ll dewpoint and relative humidity transmitter is compact for easy installation. Housed in a weatherproof enclosure, its modular design is available in a variety of mechanical configurations to accommodate a wide array of applications.
