The fluorescence sensor for dissolved oxygen is a newly developed digital online sensor that utilizes imported components, advanced production technology, and surface-mount technology. It is IP68 waterproof, and the cable is seawater-resistant. The cable is seawater-resistant. The sensor can be inserted directly into the water without a protective tube, which ensures its long-term stability, reliability, and accuracy.The fluorescence sensor for dissolved oxygen is based on the principle of inducing active fluorescence through certain physical substances. Blue light from a light-emitting diode (LED) shines on the fluorescent material inside the fluorescence cap.The fluorescent material on the inside is excited and emits red light. By detecting the phase difference between the red and blue light and comparing it with the internal calibration value, the concentration of oxygen molecules is calculated, and the final value is automatically compensated for temperature.
