product details
ME2-O3 ozone sensor is a constant potential electrolytic sensor. The electrochemical oxidation process of ozone on the working electrode is controlled by an electronic circuit to maintain the working electrode and reference electrode of the electrolytic cell at an appropriate potential. At this potential, the electrochemical oxidation or reduction reaction of ozone can occur. Due to the small Faraday current generated by oxygen during oxidation and reduction reactions, it can be ignored. Therefore, the current generated by the electrochemical reaction of the tested gas is proportional to its concentration and follows Faraday's law. In this way, the concentration of the gas to be measured can be determined by measuring the magnitude of the current.
Sensor characteristics
Low power consumption, high precision, high sensitivity, wide linear range, strong anti-interference ability, excellent repeatability and stability.
Main applications
Widely suitable for ozone detection in industrial and environmental protection fields.
