Product Description Product DescriptionThis sensor is based on polarography to measure dissolved oxygenin water. The dissolved oxygen sensor is composed of cathode and anode.The cathode is platinum electrode and the anode is silver / silver chlorideelectrode. The cathode and anode are immersed in the electrolytechamber, which is isolated from the exteral measurement environmentthrough a diaphragm, Dissolved oxygen diffuses to the cathode throughthe diaphragm and is reduced on the cathode to generate current. Thereduction current is positive with the transfer rate of dissolved oxygeninto the electrolyte. At a given temperature, the current is proportional tothe partial pressure of oxygen in the water. lt can be used for thedetermination of dissolved oxygen in aquaculture river monitoring,sewage treatment, swimming pool and other water.Features-Adopt the principle of polarography, the test water sample needs to maintain fluidity.-With appropriate oxygen permeable membrane, reference electrode and electrolyte, the electrode hasbetter measurement accuracy and stability.-Built in temperature sensor with automatic water temperature compensation function.-Supports MODBUS /RS485 output.Product ParametersProjectSpecificationsSensor materialPlatium cathode, silver/silver chloride reference electrodeWorking condition0-40oCTemperature elementNTC 10KResponse time≤90sMeasuring range0-20mg/L, 0-200%Installation mode3/4" NPT thread, flow-through or submersible mountCableStandard 5 meters(OEM available)Measuring principleTwo electrode polarographyCalibration2 points calibrationStorage temperature0-50oC(Dry without electrolyte)Power supply12~24VDCData outputMODBUS/RS485IP gradeIP68Company Profile
