DewTech 390 Low Dew Point Hygrometer
±0.2°C DP accuracy, dual alarm capability, available with standard or chemical resistant sensor
The Edgetech Instruments Model DewTech 390 is a Precision Low Dew Point Hygrometer which offers measurement of extremely low Dew Point 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 dew point 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.
