Web11 de abr. de 2024 · Generally, hygrometers, or cooled mirrors, have been the conventional air measurement tools used for precise dew point measurement. The device is considered to be a humidity transfer standard. The process entails cooling a mirror until water vapor begins to condense on the surface. The temperature of the mirror is measured. WebThe Dew Point temperature is always lower than the Dry Bulb temperature and will be identical with 100% relative humidity (the air is at the saturation line). As air temperature changes the Dew Point tends to remain …

WebThe original technique for measuring hydrocarbon dew point was to use a chilled mirror dew scope. This is a manual method which requires a skilled operator to view the formation of condensate on a chilled mirror and use their judgement to determine the dew-point temperature.
