Why select a Chilled Mirror Hygrometer?
The chilled mirror hygrometer (CMH) dew point has several distinct advantages over other water vapor sensing technologies: A CMH provides one of the few truly direct physical measurements of humidity. It is recognized as the most precise method of determining the water vapor content of a gas above 5% RH. Use it when you need maximum precision of measurement. The CMH’s optical sensor is a totally inert device. The sample gas contacts glass and non-reactive metals. Thus, it can be easily cleaned and can last indefinitely. Use it when the gas sample contains contaminants and particulates, which would damage other types of humidity sensors. Unlike polymer RH sensors, lithium chloride dew cells, and other chemically-based sensors, a CM sensor does not lose its calibration. Use it when you need long-term calibration stability. The dew/frost point temperature defines the saturation point for the water vapor in the gas. From this unique equilibrium temperature, all other reporting formats of g
