Product Name: Fluorescence Dissolved Oxygen Electrode Model NO.: E-Do Function: Over Voltage Protection Cooling System: Radiator Type: Do Electrode Test Item: Do Method: Fluorescence Range: 0-20mg/L Trademark: LOHAND Transport Package: 1 Piece/Box Specification: 1 piece/box Origin: China HS Code: 9027900000 Product Description Fluorescence dissolved oxygen electrodeIntroduction:This sensor is coated with a luminescent material. Green light from an LED is transmitted to the sensor surface. The green light excites the luminescent material. As the material relaxes it emits red light. The time it takes for the red light to be emitted is measured. Between the flashes of blue light, a red LED is flashed on the sensor and used as an internal reference. Increased oxygen in the sample decreases the time it takes for the red light to be emitted. The time measurements correlate to the oxygen concentration.ParameterMeasuring rangeAccuracyResolutionTemp. compensationWorking temp.Digital interface0-20.00mg/L 0 to 200 % air saturation±1% F.S0.01mg/LDS18B20 digital temp sensor0-40ºCMODBUS/RS485Application:The sensor is used for testing the dissolved oxygen in water, which can monitoring in many fileds like sewage treatment plant,aquaculture,food/chemical industry/power plant water treatment, the water environmental of river/lake/sea and so on.DimensionInstallation
