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 MBW 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 MBW 973 dew point mirror are supplied a tough transport case that protects this valuable instrument when moving around site or when shipped for calibration.
