Principle Introduction
| MEWOI-MIX8412 Ozone Gas Sensor is an electrochemical O3 sensor developed by Mixsen. It uses the principle of electrochemistry. There is a reference electrode inside the sensor, which greatly improves the stability of the sensors. When the sensor senses the ozone, the working electrode and the counter electrode react with the redox reaction, through measure the current to get the concentration of ozone. |
Features
*High selectivity & sensitivity to O3 *High accuracy *Linear output *Environmental protection design |
Application
* Industrial monitors * Leakage detection for sterilization equipment * Portable gas detector * Real time monitoring of ozone concentration in disinfector and distribution cabinet; * Ozone concentration monitoring in industrial, commercial, atmospheric environmental protection and other fields. |
