The MBW Calibration 973 dew point hygrometer is a portable instrument equipped with an integral measuring head for measurement of dew/frost point in air and other gases. Utilizing the chilled mirror principle, the 973 provides drift free and accurate humidity measurements.
The 973 accurately measures pressure and temperature and has added features that enable alternative humidity parameters such RH, ppmv, vapor pressure and absolute humidity. Users can quickly self-check the 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.
