The Edgetech Instruments DewGen is a high accuracy dew/frost point generator that may be used as a stand-alone device to easily create a known and precise dew or frost point calibration gas. It can go wherever needed, in the laboratory or in the field. With no electric power requirement, it is intrinsically safe for all locations.

When the DewGen’s output is connected to a NIST traceable dew/frost point hygrometer, such as the Edgetech Instruments DewMaster, the result is a traceable and highly accurate dew/frost point gas generator system for testing and calibrating less accurate dew/frost point sensors, or for use in any R&D application.

A divided flow system, combined with a plane surface saturator, allows the user to select any dew or frost point from -80°C frost point, less than one ppm of water vapor, to nearly saturation. The user provides a source of dry gas, such as dry air or a tank of dry nitrogen, for the “dry” carrier gas.

Mixing ratios of up to 100,000 to 1 allow selection of frost points down to -80°C and dew points up to +15°C, selectable in 1°C increments. When the DewGen is coupled with a NIST traceable chilled mirror hygrometer, the result is an extremely cost effective dew/frost point calibration standard at a fraction of the cost of other types of calibration systems.
