The Edgetech Instruments DewTech 390 is intended for laboratory use and has all the attributes needed for that purpose. Other hygrometers with specifications similar to the DewTech 390 are priced much higher without offering technical or useful advantages. The DewTech 390 provides the high value and top performance Edgetech Instruments’ products are known for.

At the core of the DewTech 390 is a primary method, three stage Peltier cooled chilled mirror sensor. For peak efficiency, the performance of the Peltier is maximized through an integral cryo-cooling refrigeration system giving it very wide rangeability.

The DewTech 390 is ideal for metrology labs, scientific research, low dew/frost point process measurements or any application where high precision measurement of dew/frost point over a wide range with fast response and high stability are required.

The DewTech 390 is supported in the USA in a modern, ISO 9001:2015 registered facility with ISO/IEC 17025:2005 accredited calibration laboratory. It is delivered with a UKAS traceability certificate.
