The BGT-WDO(K2) fluorescence dissolved oxygen sensor is designed based on the principle of quenching fluorescence by specific substances in physics. When excitation light strikes the fluorescent material on the surface of the fluorescent membrane, it is excited and emits fluorescence. The quenching time of this fluorescence is affected by the concentration of oxygen molecules on the membrane surface. By measuring the phase difference between the fluorescence and the excitation light and comparing it with an internal calibration curve, the oxygen concentration is calculated and the final value is compensated for temperature and salinity.
