What are the structures and principles of the fluorescence dissolved oxygen meter?

The fluorescence method dissolved oxygen meter is used for the monitoring of various process points in the sewage treatment plant: including surface water monitoring such as regulating tanks, aeration tanks, aerobic and anaerobic digestion tanks and effluent monitoring. If you need to know more about fluorescence dissolved oxygen instruments, you can contact BOQU instrument technicians. BOQU instruments are an enterprise specializing in the production and sales of water quality monitoring instruments and fluorescence dissolved oxygen instruments. The fluorescence dissolved oxygen meter they provide has the advantages of high sensitivity, good quality and considerate service. So what are the structures and principles of the fluorescence dissolved oxygen instrument? Let's take a look together. The fluorescent dissolved oxygen meter has a layer of fluorescent material. The blue light emitted by the LED light source is irradiated on the fluorescent material, and the fluorescent material is excited and emits red light. A photocell measures the time it takes for a fluorescent substance to return to its ground state from emitting red light. This time is only related to the emission time of blue light and the amount of oxygen. The probe also has an LED light source, which emits red light at the same time as blue light emission, as a reference for blue light emission time. The more oxygen there is around the sensor, the less time the phosphor has to emit red light. Optical system: modulation light source, optical transmission system. Fluorescent sensitive membrane: fluorescent molecules, fluorescent molecule carriers. Probe: optical path system, fluorescent sensitive film and optical detection system. Optical detection system: light filtering, photocurrent detection, amplification and calculation. The fluorescence method dissolved oxygen meter adopts the innovative fluorescence method to replace the traditional membrane electrode, without replacing the diaphragm and electrolyte, which reduces the maintenance workload and improves the working reliability. It is especially suitable for harsh working conditions in the field of sewage treatment. In addition, the fluorescence sensor does not consume oxygen, so there is no requirement for flow rate and agitation, and it is not interfered by substances such as sulfide.
