Chilled Mirror Hygrometer Information

The measurement of the water vapor content of a gas by the dew-point technique involves chilling a surface, usually a metallic mirror, to the temperature at which water on the mirror surface is in equilibrium with the water vapor pressure in the gas sample above the surface. At this temperature, the mass of water on the surface is neither increasing (too cold a surface) nor decreasing (too warm a surface).

Chilled Mirror Hygrometers Sampling & Accuracy

The absolute accuracy of the condensation-type (chilled mirror) hygrometer is exceeded only by the gravimetric train, an elaborate absorption system maintained as the primary standard for humidity measurements. Over the mid-range of dew point temperatures (40C), the uncertainties of chilled mirror hygrometer measurements are in the order of one part in 100.
