Product Name: Fluorescence Dissolved Oxygen Sensor (DOF-4850S) Model NO.: DOF-4850S Application: Chemical Instrument, Water Treatment Warranty Period: One Year Waterproof Rate: IP68/NEMA6p Trademark: JIRS Transport Package: Carton Specification: 49.5*251.1mm Origin: China HS Code: 9028901000 Product Description Fluorescence Dissolved Oxygen SensorCode:DOF-4850SIntroduction:The dissolved oxygen sensor measures the dissolved oxygen by the fluorescence method, and the emitted blue light is irradiated on the phosphor layer. The fluorescent substance is stimulated to emit red light, and the oxygen concentration is inversely proportional to the time when the fluorescent substance returns to the ground state. By using this method to measure the dissolved oxygen, it will not produce oxygen consumption, thus assuring data stability, reliable performance, no interference, and simple installation and calibration.The product is widely used in sewage plant, water plant, water station, surface water, farming, industry and other fields.Main technic paramentersSpecificationsDetailsSizeDiameter 49.5mm*Length 251.1mmWeight1.4KGMain MaterialSUS316L+PVC (Ordinary Version), Titanium Alloy (Seawater Version)O-ring: Fluoro-rubberCable: PVCWaterproof RateIP68/NEMA6PMeasurement Range0-20mg/L(0-20ppm)Temperature: 0-45ºCIndication ResolutionResolution:±3%Temperature: ±0.5ºCStorage Temperature-15~65ºCEnvironment Temperature0~45ºCPressure Range≤0.3MpaPower Supply12 VDCCalibrationAutomatic air calibration,Sample calibrationCable LengthStandard 10-Meter Cable, Max Length: 100 MetersWarranty Period1 Year
