Description

The 973 Dew Point Mirror also measures pressure and temperature with high accuracy and includes features that enable alternative humidity parameters such as 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 the site or when shipped for calibration.
