Dissolved oxygen is measured by fluorescence method, the blue light emitted is irradiated on the fluorescent layer, the fluorescent substance is excited to emit red light, and the oxygen concentration is inversely proportional to the time for the fluorescent substance to return to the ground state. This method is used to measure dissolved oxygen, no oxygen consumption will occur during the measurement, the data is stable, the performance is reliable, there is no interference, and the installation and calibration are simple. This product is widely used in the monitoring of dissolved oxygen in sewage plants, water plants, water stations, surface water, aquaculture, industry and other fields.
