Model 973S Dew Point
Mirror Hygrometer

Standard Dew Point Chilled Mirror Analyzer

Integrated 973S Dew Point Mirror Hygrometer

For Continuous Dew/Frost Point in Air and Other Gases

Our MBW CALIBRATION™ MODEL 973S™ Dew Point Chilled Mirror Analyzer with integrated sample pump, external temperature measurement and transport case. For many years this was the standard version, hence the MODEL 973S designation. As a transfer standard, it remains a popular option thanks the high stability of the integrated measuring head, integrated 0.1% pressure sensor, and high precision temperature measurement to enable calculation of relative humidity.

The MODEL 973S Dew Point Chilled Mirror Analyzer is a portable instrument designed for the measurement of dew point in a variety of gases. It is commonly used in industries where the moisture content of gases is critical to the production process or end-use application.
