The Edgetech DewTrak II is a low cost optical chill mirror dew point hygrometer, designed to continuously measure the moisture content in gases. It uses the chill mirror dew point temperature condensation principle to determine the water vapor concentration in gas mixtures.

The DewTrak II can be configured to measure dew point, temperature and relative humidity and is available in a variety of housing packages for wall, duct, remote and pipe applications.

The DewTrak II has an accuracy of ±0.2°C for dew point, ±0.1°C for air temperature (optional) and ±0.5% for RH (typically). The unit also features two analog outputs, two programmable relays, RS232 (bi-directional) and a backlit LCD display (optional).
