BL783 Chilled Mirror Hygrometer
Cooled mirror hygrometry is a precise technique for determining the water vapor content in gases by directly measuring the dew point or frost point temperature. With this technique, a metallic mirror is cooled until it reaches a temperature at which a thin layer of condensation begins to form. The dew layer is detected optically and the mirror is maintained at that temperature. The mirror temperature, measured with a PRT, is an accurate indicator of the dew or frost point.
