PROBEST
90268090
China Probest Digital Online Optical Real-Time Water Monitoring Sensor Dissolved Oxygen Test Sensor Probe Instrument Manufactureradopts fluorescence method to measure dissolved oxygen. The cap of the sensor is coated with a luminescent material. Blue light from an LED illuminates the luminescent chemical. The luminescent chemical instantly becomes excited and releases red light. The time and intensity of red light are inversely proportional to the concentration of oxygen molecules, So the concentration of oxygen molecules is calculated.
n Features
u Won't produce oxygen consumption when measuring and no requirement of flow rate and stirring.
u Factory calibration, not need calibration for a year and can carry out field calibration.
u Digital sensor, high anti-jamming capacity and far transmission distance.
n Applications
DO online monitoring of different technological processes such as regulating reservoir, biochemical pool and effluent of sewage treatment plant.
DO online monitoring of water plant, surface water, industrial process water and aquaculture and etc.
