Dew Master Chilled Mirror Hygrometer 00876
The DewMaster is a laboratory grade, high precision, field proven instrument with multiple available sensor configurations and wide applicability. Available sensors include the high performance, chemically resistant Model X3 and the remotely mounted Model DX drift free chilled mirror sensors.
 
This fast, multi-function, high precision chilled mirror hygrometer continuously monitors 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 user friendly, easy access sensors, automatic startup and balance, and self-diagnostics. Unlike other dew/frost point sensor types, chilled mirror sensors are easily cleaned when necessary and rarely require replacement.
 
Applications range from use as a calibration standard, to monitoring moisture content in continuous industrial processes. Dew/frost point ranges are from -40°C to +95°C with 60°C temperature depression, to -90°C to +95°C with 125°C temperature depression, with many ranges and sensor options available. The Model X3 can be air, fan or liquid cooled and the Model DX can be remotely mounted for area monitoring or used as an insertion sensor.
