Dew Definition & Meaning - Merriam-Webster

WebChilled mirror technology can offer the highest accuracy over a wide range of dew points. The operating principle is based on the fundamental definition of dew point – cooling a volume of air until condensation forms. A gas sample passes over a metallic mirror surface which is chilled by a cooler. Light is then directed WebWhen this happens, dew forms on surfaces that aren't warmed by the heat radiated from the ground.

WebModel CMH Chilled Mirror Hygrometer accurately measures the dewpoint of a gas by cooling a mirrored surface, over which the gas flows until a layer of dew forms on the surface. The Chilled Mirror Dew Point Hygrometer utilises a 3-stage cooler combined with an integral refrigeration unit to measure the dewpoint in gases from below -95 °C to 20 ... WebThe optical sensing bridge detects the change in light level when dew or frost forms on the mirror. Subsequent cycles of negative feedback controlled heating and cooling refine the result to a highly accurate constant reading of sample dew point. This technique is a primary measurement of the water vapour content of the gas.
