RDO-206A Online Fluorescence Dissolved Oxygen Sensor

RDO-206A Online Fluorescence Dissolved Oxygen Sensor

The RDO-206A integrated online fluorescence dissolved oxygen sensor is designed based on the quenching principle of excitation fluorescence by specific substances in physics. When the excitation light is irradiated onto the fluorescent substance on the surface of the fluorescent film head, the fluorescent substance is excited and emits fluorescence. The extinguishing time of the fluorescence is affected by the concentration of oxygen molecules on the surface of the fluorescent film head. By detecting the phase difference between fluorescence and excitation light and comparing it with an internal calibration curve, the concentration of oxygen molecules can be calculated, and the final value can be output after temperature and salinity compensation.
