The Edgetech 200M DewTrak meteorological humidity system consists of a thermally shielded enclosure for the dew point and ambient temperature sensors, a microprocessor-based electronic control unit and 25 feet of interconnecting cable. The Edgetech 200M is a complete instrument for the measurement of atmospheric dew point, ambient temperature, %-relative humidity and other psychometric variables.

Utilizing a very reliable optical chilled mirror sensing technology, Edgetech 200M DewTrak meteorological humidity systems provide a primary measurement of dew point and is NIST traceable. The Edgetech 200M is ideally suited for installations requiring continuous, automatic and unattended measurement of humidity over a very wide range. Automatic Balance Control (ABC) cycle corrects the light reducing effects of mirror contaminants and allows for continuous monitoring and virtually maintenance-free operation.

The Edgetech 200M measures dew point in °C or °F and is available with a two stage dew point sensor. The Edgetech 200M reduces the need for cleaning by the incorporation of self-diagnostics which indicates when, and if, maintenance is required.
