Digital Fluorescent Dissolved Oxygen Electrode uses green light excitation fluorescence lifetime detection technology. Greenlight 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 exciting red light fluorescence lifetime is dissolved in water The oxygen concentration is inversely proportional, so the dissolved oxygen concentration in water can be calculated by measuring the excited red fluorescence lifetime.
