Principle Introduction
Xtester--MIX8421 is an electrochemical SO2 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 sulphur dioxide, the working electrode and the counter electrode react with the redox reaction, through measure the current to get the concentration of sulphur dioxide.

*High selectivity & sensitivity to SO2

*High accuracy

*Linear output


* Industrial SO2 monitors leakage detectio
