WebThe dew point is the temperature to which air must be cooled to become saturated with water vapor, assuming constant air pressure and water content. When cooled below the dew point, moisture capacity is reduced … 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
