Model 973-Sf6

Portable Chilled Mirror Hygrometer

High-Performance Hygrometer Measures Both Spot and Continuous Dew/Frost Point in Air and Other Gases – Laboratory Precision – Field Ready

The MBW CALIBRATION™ MODEL 973-SF6™ Dew Point Chilled Mirror Analyzer is a portable instrument equipped with an integral measuring head for both spot and continuous measurement of dew/frost point in air and other gases. Based on the chilled mirror principle, the 973 provides fundamental, drift free and precise humidity measurement. For many applications it is a transfer standard.

Find out why we are different.

The 973 also measures pressure and temperature with high accuracy and includes features that enable alternative humidity parameters such RH, ppmv, vapor pressure and absolute humidity. Unique features enable fast response in spot check applications and users can self-check instrument calibration stability using the integrated Ice-Test function. All versions of the 973 are supplied a tough transport case that protects this valuable instrument when moving around site or when shipped for calibration.
