Digital Fluorescence Dissolved Oxygen Electrode uses green light excitation fluorescence lifetime detection technology. Green light is irradiated on the fluorescent substance to cause the fluorescent substance to excite red light. Due to the quenching effect of oxygen molecules in water, the excited red light fluorescence lifetime is dissolved in water The oxygen concentration is inversely proportional, so that the dissolved oxygen concentration in water can be calculated by measuring the excited red fluorescence lifetime.
