Introduction
The dissolved oxygen sensor uses fluorescence to measure the dissolved oxygen. The sensor is covered with a layer of fluorescent material. When the blue light emitted by the sensor illuminates the fluorescent substance on the fluorescent cap, the fluorescent substance is excited to emit red light, and since the oxygen molecule can carry away the energy (quenching effect), the time and intensity of the excited red light and the concentration of the oxygen molecule become. In inverse proportion, the concentration of dissolved oxygen in water can be obtained by calculation.
This product is widely used in the DO online monitoring of the regulating tank, biochemical tank and effluent of sewage treatment plant.DO online monitoring in waterworks, surface water, water used in various industrial production processes, aquaculture and other industries.
