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.

Precautions for selecting ozone sensors

1. The selection of sensors is very important. If the selection of sensors does not match the usage site, it can lead to many situations. Therefore, when selecting sensors, the following points must be noted:

2. Is the temperature, humidity, and pressure in the gas detection environment within the normal detection range of the sensor? Otherwise, a pre-processing system needs to be installed at the front end for the sensor to function properly;

3. Is the concentration in the gas detection environment within the normal detection range of the sensor? Otherwise, a higher range sensor should be selected;

4. When choosing a gas sensor, do the required range and resolution meet your requirements;
