1Product Overview
PDM483Precision Dew Point MetersBased onOptical Cold MirrorPrinciple-based temperature and humidity measurementEquipmentThisPrincipleDifferent from measuring humidity indirectly through changes in capacitance and resistance, it is a method based on humidity./Dew Point DefinitionDirect measurement instruments.
Humidity measuring instruments can be categorized by principle into cold mirror, fully absorbing electrolytic, thin-film capacitive, resistive, wet-bulb, and mechanical types. Among them, fully absorbing electrolytic dew point meters are generally used for low humidity range measurements, while resistive, wet-bulb, and mechanical hygrometers are commonly employed.GenerallyFor measuring relative humidity, cold mirror dew point meters and thin film capacitive hygrometers are not only suitable for low humidity measurements but also for medium to high humidity, i.e., relative humidity measurements. The aforementioned various principlesMethodEach has its pros and cons; among them, the cold mirror dew point hygrometer.Due to havingHigh accuracy, strong reliability, direct measurementFeaturesWidely used for standard transmission.
