O2-A2 Electrochemical Oxygen sensor For Medical Field Firefighting and Safety Monitoring
Working Principle:
It operates based on the electrochemical principle. Oxygen molecules in the measured gas enter the sensor and participate in redox reactions at the sensing electrode. These reactions generate an electrical current, and the magnitude of this current is proportional to the oxygen concentration in the gas, enabling the determination of oxygen levels.
