Life and Warranty 2-year lifespan in air; Warranty period 12 months after delivery Reliable performance under original sealed storage conditions Working principle
Based on the three-electrode electrochemical principle: After CO gas diffuses into the sensor, an oxidation reaction occurs at the working electrode, generating an electric current. The magnitude of the current is proportional to the concentration of CO; the auxiliary electrode inhibits interference reactions, and the reference electrode stabilizes the working potential. Through circuit conversion, a readable concentration signal is obtained, enabling precise detection.
