DRAGINO - Accessories - Sensor for water quality/el. Conductivity - DO Sensor - DR-DO1

The dissolved oxygen fluorescence sensor is a newly developed online digital sensor that uses imported components, advanced production technology and surface mount technology.

It is IP68 waterproof, and the cable is seawater-proof. The cable is seawater-proof. The sensor can be directly inserted into the water without a protective tube, which ensures the long-term stability, reliability and accuracy of the sensor.

The dissolved oxygen fluorescence sensor is based on the principle of quenching active fluorescence by 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 temperature and air pressure.
