Model BL784 Chilled Mirror Dew Point Meter SPECIFICATION ■ ■ ■ ■ ■ ■ ■ ■ ■ 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 dew or frost point. Dew/frost 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 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 Balun Technology Co., Ltd Add: 1322, F/3, Bldg 1, 33 Zique Rd, Haidian, Beijing100095, China Dew point range: -20 to +85℃ , (4.41~100%RH @20℃ ) Dew point accuracy: ±0.20℃ (calibration: -15℃ to +20℃ ) Dew point resolution: 0.01℃ Dew point reproducibility error: ±0.05℃ Temperature range: -45℃ to +90℃ Temperature accuracy: ±0.10℃ (calibration: -10℃ ~60℃ ) Temperature resolution: 0.01℃ Temperature reproducibility error: ±0.05℃ Working environment: -20℃ to +60℃ , 10%RH to 90%RH, 101.325kPa (custom atm. is option) Mirror temperature measurement:4 wire PT100 1/3B Depression: Single stage, 45℃ at 25℃ Probe material:SUS304 stainless steel Cable material: Polyurethane material with shielding layer Response time: Max cooling 0.8℃ /s, + 15s balance time Sampling airflow rate: 0.1~1NL/min (The volume of ventilation is inversely proportional to the dew point) Cooling type: Peltier cooling Output signal: Modbus RTU, USB Power supply:100-24VAC 35W or USB Type-C 5V/2A 10W Ingress protection grade:IP54 Dimension: 160mm (W) x 165mm (D) x 85mm (H) Weight: 4kg includes standard accessories BL784 Chilled mirror dew point meter Single stage chilled mirror dew point sensor 2 meters dew point sensor connection cable USB2.0 into USB type-C cable Standard AC Power cord User manual Carrying case OPTIONAL ACCESSORIES AND SERVICES ■ ■ ISO17025 accredited calibration certificate 5 meters dew po
