Model 973S

Integrated Chilled 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 973S MODEL 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.
