Chilled Mirror Dew Point Hygrometer . Chilled mirror hygrometer, it uses proven optically detected chilled mirrors to measure the dew point or frost point of a gas. W hen it begins to appear, the te mperature. Chilled Mirror Dewpoint Hygrometer For Industrial Process Application from www.indiamart.com Optisonde specifications wall mount 3.7 in (94 mm) 8.84 in (224.5 mm) 8 in (203.2 mm) 3.3 in (83.8 mm) bench top W hen it begins to appear, the te mperature. There are a few differences with this diy chilled mirror hygrometer compared to a commercial unit.

Chilled Mirror Dew Point . The optica measures dew point temperature by regulating the temperature of a polished metal mirror by the use of optical feedback such that a constant mass of dew or frost is maintained. Dew condensation is determined optically; Panametrics Optica Series Chilled Mirror Hygrometer Dew Point Meters from www.instrumart.com The optica simultaneously measures water dew point, temperature, and pressure, measurements all traceable to national standards and can display those in a variety of user selectable units. The dewmaster uses the chilled mirror (cm) dew point temperature condensation principle to determine the water vapor concentration in gas mixtures, and a precision platinum resistance thermometer to measure the mirror temperature. Mirror dew point meter gases with different moisture content will condense on.
