The fluorescence sensor for dissolved oxygen is a newly developed digital online sensor that uses imported components, advanced production technology and surface mounting 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 the long-term stability, reliability and accuracy of the sensor.The fluorescence sensor for dissolved oxygen is based on the principle of inducing active fluorescence through certain physical substances.The blue light of a light-emitting diode (LED) shines on the fluorescent material on the inside of 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 temper
