4S-O2 Electrochemical Oxygen Sensor
4S-O2 Electrochemical Oxygen Sensor
Product details
product details
The electrochemical 4S-O2 oxygen sensor is based on the principle of electrochemistry, which uses the measured gas to undergo corresponding oxidation-reduction reactions and release charges on the working electrode and counter electrode of the sensor, and forms a current through an external circuit. The magnitude of the current is proportional to the gas concentration, thus achieving quantitative measurement of the target gas.
Sensor characteristics
Low power consumption, high precision, high sensitivity, wide linear range, strong anti-interference ability, excellent repeatability and stability.
Main applications
Widely applicable for oxygen concentration detection in the industrial field.
