Electrochemical Oxygen Sensor 4S-O2

Summary:

The electrochemical 4S-O₂ oxygen sensor is based on the principle of electrochemistry, using the measured gas to undergo a corresponding redox reaction on the working electrode and the counter electrode of the sensor and release the charge, and form a current through the external circuit. The magnitude of the current is proportional to the gas concentration, thereby Realize quantitative measurement of target gas.
