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.

Features:

• High Reliability: It is a leak - free sensor, ensuring stable and accurate measurements. The output changes by less than 1% over a period of 3 months, guaranteeing consistent performance.
• Fast Response: With a T90 (the time required to reach 90% of the final value) of less than 15 seconds when transitioning from 20.9% to 0% oxygen concentration, it can quickly detect changes in oxygen levels.
• Low Humidity and CO₂ Sensitivity: The humidity has less than a 0.7% impact on the measurement results, and its sensitivity to CO₂ is less than 0.1%. It can resist humidity levels of up to 99%, making it suitable for use in various environmental conditions.
• Long Warranty and Operating Life: It comes with a 2 - year warranty. Its operating life can exceed 24 months until the output decays to 85% of the original output at 20.9% oxygen concentration.

Applications:

• Industrial Fields: Widely used in coal, steel, and petrochemical industries. For example, in coal mines, it can monitor the oxygen content in the working environment to ensure the safety of miners. In the steel and petrochemical industries, it helps optimize combustion processes by accurately measuring oxygen levels in furnaces or reactors, improving energy efficiency and reducing pollutant emissions.
• Medical Field: Applied in medical equipment such as oxygen alarms and atmosphere analyzers to ensure the proper oxygen concentration in medical settings, which is crucial for patient treatment and safety.
• Firefighting and Safety Monitoring: Used in handheld gas detectors for firefighters and safety personnel. It enables them to quickly detect oxygen concentration in potentially hazardous environments, helping them make informed decisions to protect their safety.
