ME2-O2 Oxygen Gas Sensor High Precision Precision With 10kΩ Recommended Load Resistance
The ME2-O2-Ф20 electrochemical sensor is based on the electrochemical principle and detects gas concentration by measuring current. The sensor uses the electrochemical oxidation process of the target gas on the working electrode in the electrolytic cell. The current generated by the target gas in the electrochemical reaction is proportional to its concentration. Following Faraday's law, the gas concentration can be obtained by measuring the current.
