The dissolved oxygen sensor uses fluorescence to measure dissolved oxygen, the emitted blue light on the fluorescent layer, the fluorescent material receives the excited red light, and the oxygen concentration is inversely proportional to the time the fluorescent material returns to the ground state. This method is used to measure dissolved oxygen without generating oxygen consumption, stable data, reliable performance, no interference, and simple installation and correction.
