The S4-O3 ozone gas detection sensor is a constant potential electrolytic sensor. The electrochemical oxidation process of ozone on the working electrode is to keep the working electrode and the reference electrode of the electrolytic cell at an appropriate potential through the electronic circuit. At this potential, the electrochemical oxidation or reduction of ozone can occur. The concentration of the gas to be measured can be determined by measuring the current.
