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. The MODEL 973 Dew Point Chilled Mirror Analyzer 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. The MODEL 973-SF6 Dew Point Chilled Mirror Analyzer is a portable instrument designed for measuring the dew point of SF6 gas. SF6 is a commonly used insulating gas in electrical power transmission and distribution equipment, and accurate dew point measurements are crucial for ensuring the safe and reliable operation of the equipment. It vutilizes a chilled mirror dew point sensor to measure the dew point temperature of SF6 gas. The gas sample is collected from the equipment being tested and then passed through a pre-filter to remove any particulate matter.
