DewTech 390 Low Dewpoint Hygrometer

The Edgetech Instruments DewTech 390 is a precision dew/frost point hygrometer that measures extremely low frost points or trace moisture in a variety of background gases. Based on the primary method chilled mirror sensor technique, it is delivered with a NIST traceable calibration certificate and is certified in an ISO/IEC 17025 accredited calibration laboratory. At the core of the DewTech …

Features

  • A precision laboratory grade hygrometer system that measures an extremely wide range of dew/frost points in gases from as low as –90°C frost point to as high as +20°C dew point
  • Based in the primary method chilled mirror technique with all the attributes, features and certifications needed for laboratory use at an affordable price
  • Ideal for metrology labs, scientific research and 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
  • For peak efficiency the sensor’s performance is maximized by an integral cryo-cooling system
  • The DewTech 390 is supported in the USA in a modern, ISO 9001 registered facility with ISO/IEC 17025 accredited calibration laboratory and is delivered with a UKAS traceability certificate.

PPM2 Portable Trace Moisture Transmitter

The Edgetech Instruments Model PPM2 is a portable battery powered trace moisture analyzer designed specifically for monitoring moisture levels in dewpoint and ppm units. This trace moisture analyzer utilizes an electrochemical (P2O5) sensor in combination with a proprietary semi permeable diffusion membrane. The principal of operation applies the Faraday’s Law of Electrolysis which measures the dissociation current making it a …
