Action principle:

The fluorescence method electrode adheres a chemical film to the top of the optical cable, and oxygen ions react with the chemical film to change the film's light transmission ability. At this time, the fluorescence reaction characteristics of the film will depend on the concentration of oxygen, and the fluorescence reaction is maximum when there is no oxygen in the water. Fluorescence reaction and O₂After ion reaction, it will appear in a stable state.

The signal response output is non-linear and sensitive to low oxygen concentrations. However, light sensors can still detect oxygen levels in water ranging from 0% to 100%. There is no oxygen consumption during the reaction process, and it will not affect the sensitivity of the sensor. After activation, the signal of the sensor will be faster and more stable. This type of sensor is suitable for monitoring dissolved oxygen in water during the process and in real-time online.
