Page 3: Background Meaning And Working Principle
Working principle S-RJY-01 integrated online fluorescence method dissolved oxygen sensor is designed based on the principle of quenching excitation fluorescence by specific substances in physics. When the excitation light is irradiated on the fluorescent substance on the surface of the fluorescent film head, the fluorescent substance is excited and emits fluorescence, and the extinguishing time of the fluorescence is affected by the concentration of oxygen molecules on the surface of the fluorescent film head. -
