Chilled mirror dew-point meter BL784

Chilled mirror dew point meter is a precise technique for determining the water vapor content is gases by directly measuring dew point or frost temperatures. Using this technique a metal mirror is cooled until it reaches a temperature at which a thin layer of condensation begins to form on it. The dew layer is detected optically, and the mirror is held at that temperature. The mirror temperature, measures with a PRT, is an accurate indicator of the dew or frost point. FEATURES • Dew point range -20℃ to +85℃ • Accuracy to ±0.20 ℃ dew point • Dynamic balance control for contamination • Simultaneously measures dew point, temperature, relative humidity, absolute humidity, specific humidity, enthalpy, vapor pressure and volume ratio (ppmV). • Real time data logging and curve display • MAX value and MIN value are recorded • AC or alternative DC power supply • MODBUS RTU and USB communication • 4 inch touch screen APPLICATION • Reference standard in calibration lab • Inlet air measurement for engine testing • Heating ventilation and air conditioning test • Environment monitoring in clean room • Humidity control for metallurgical processes • Coating process monitoring in pharmacy • Reference humidity instruments for climatic and environmental chambers
