In today's fields of industrial safety, environmental monitoring, and health management, accurate detection of oxygen concentration is crucial. Tensensor's MQ-E2-O2 oxygen sensor, with its superior electrochemical sensing technology, stable output performance, and wide application adaptability, has become the preferred high-reliability oxygen monitoring solution for many industries.

MQ-E2-O2-φ20 Electrochemical O2 Sensor

Advanced Technology, Precise Monitoring

    The MQ-E2-O2 sensor employs a galvanic cell-type electrochemical sensing principle. It generates a current signal proportional to the oxygen concentration through the redox reaction of oxygen on the working and counter electrodes. This sensor boasts the following outstanding features:

    High Sensitivity and Stability: Output signal of 0.10±0.02mA in air, with a repeatability error of less than 2%, ensuring reliable long-term monitoring data.

    Fast Response: Response time (T90) less than 20 seconds, suitable for real-time monitoring and early warning systems.

    Wide Range Adaptability: Measuring range covers 0–25% vol., and can withstand short-term high-concentration environments up to 30% vol., suitable for various operating conditions.

    Strong Environmental Adaptability: Operating temperature range -20℃ to 50℃, humidity 15% to 90% RH, and pressure ±10% of standard atmospheric pressure, demonstrating strong adaptability.

Multi-domain applications, comprehensive protection

    Industrial safety: Oxygen alarm systems in hazardous environments such as petrochemical plants and mines to prevent oxygen deficiency or excess accidents.

    Medical and healthcare: Integrated into medical oxygen generators, breathing equipment, etc., ensuring precise and controllable oxygen output concentration.

    Environmental monitoring: Suitable for air quality detectors, underground parking lot ventilation systems, commercial air purification equipment, etc., ensuring air quality in public places.

    Vehicle systems: Used for in-vehicle air quality detection and fresh air unit control, improving driving comfort and health protection.

Reliable Design and Usage Recommendations

    The sensor employs a waterproof and breathable membrane protection structure, providing excellent dust and moisture protection. During use, please note the following:

    Avoid soldering or bending the leads to prevent mechanical damage.

    Do not expose to organic solvents, corrosive gases, or high-concentration acidic environments.

    Avoid vertical air intake during installation; keep the vent surfaces clean and unobstructed.

    Keep the electrodes disconnected during storage and avoid encapsulation with high-temperature sealing materials.
