The Edgetech Instruments Model DewTech 390 is a Precision Low Dewpoint Hygrometer which offers measurement of extremely low Dewpoint or Trace Moisture for a variety of background gases at a very attractive price. Based on the Primary Standard Chilled Mirror measurement technique, it provides absolute knowledge of dewpoint and is provided with a NIST traceable calibration certificate.

At the core of the DewTech 390 is a three stage, peltier cooled chilled mirror sensor. For peak efficiency, the performance of the peltier is maximized through an integral cryo-cooling refrigeration system. Ideal for metrology labs, scientific research and process measurements. Standard configurations include Benchtop or 19 inch Rack Mount. The DewTech 390 features a user-friendly display panel, an EZ access sensor, multiple outputs and alarm capability.
