Product Announcement from Edgetech, Inc.

DewMaster High Precision Chilled Mirror Hygrometer-Image

The Edgetech Instruments DewMaster is a laboratory grade, high precision dew/frost point moisture analyzer with multiple available sensor configurations and wide applicability to fit all budgets. Available sensors can be air, fan or liquid cooled to fit the required dew/frost point range. Applications range from use as a calibration standard to monitoring moisture content in continuous industrial processes.

The DewMaster is a fast, multi-function chilled mirror hygrometer for continuously monitoring the dew/frost point temperature, parts per million water vapor by volume or percent relative humidity in gas streams. Based on the primary method chilled mirror measurement technique, it features a user friendly easy access sensor, automatic startup, auto-balance, self diagnostics, analog outputs, serial interface and alarms. Unlike other dew/frost point sensor types, chilled mirror sensors are easily cleaned and rarely require replacement.
