Intelligent dissolved oxygen gauge consists of a solometer and an extreme spectrum oxygen electrode, where the electrode is the core part of the measurement, the electrode is wrapped by a silver wire anode wrapped around a platinum cathode immersed in a protective cover (measuring head) filled with a certain concentration of potassium chloride electrolyte, the protective cover bottom is a Teflon dissolved oxygen film that allows only oxygen in the solution to penetrate, when a 700mV polarization voltage is applied, the penetrating oxygen in the membrane will generate hydrogen ions in the cathode, and the anode will deposit silver chloride, reaction to generate current, its strength is proportional to the oxygen content in the sample, the instrument converts the measured current value to the dissolved oxygen concentration value and shows it.
