AMT/-DO300
Online Fluorescence Method Dissolved Oxygen Sensor
It is designed based on the quenching principle of specific substances on excited fluorescence in physics. When the excitation light irradiates the fluorescent substance on the surface of the fluorescent membrane head, the fluorescent substance is excited and emits fluorescence. The extinction time of the fluorescence is affected by the concentration of oxygen molecules on the surface of the fluorescent membrane head.
impact. The concentration of oxygen molecules can be calculated by detecting the phase difference between the fluorescence and the excitation light and comparing it with the internal calibration curve, and the final value is output after temperature and salinity compensation.
