In today's context of increasing emphasis on industrial safety, environmental monitoring, and healthy living, accurate oxygen concentration monitoring has become a crucial link in ensuring safe production and improving quality of life. The Tensensor's MQ-E2-O2 oxygen sensor is becoming an indispensable core component in various gas detection devices due to its superior performance and wide application adaptability.

MQ-E2-O2-φ20 Electrochemical O2 Sensor

Superior Performance, Reliable Choice

    The MQ-E2-O2 employs a galvanic cell-type electrochemical sensing principle. It generates current through the redox reaction of oxygen on the working and counter electrodes, achieving a linear output of concentration and signal. It features high sensitivity, strong stability, rapid response (T90 < 20 seconds), and a wide linear range (0~25%vol). Even within a wide temperature range of -20℃ to 50℃ and a humidity range of 15% to 90%RH, it maintains consistent output with a repeatability error of less than 2% and long-term drift controlled within 5%, ensuring continuously reliable monitoring data.

Multi-Scenario Integration, Wide Application

    This sensor is not only suitable for oxygen alarm systems in industrial fields such as petrochemicals and mining safety, but also plays an important role in medical oxygen generators, air quality detectors, underground parking lots, and commercial air purification equipment. Simultaneously, with the increasing demand for in-vehicle air quality management, the MQ-E2-O2 is also widely used in vehicle air detection and fresh air systems, providing a healthier breathing environment for drivers and passengers.

Intelligent Compatibility, Easy Integration

    The sensor is recommended to use a 100Ω load resistor, ensuring a stable and clear output signal, facilitating integration with various data acquisition circuits and control systems. Its compact structure and simple installation, coupled with detailed application precautions—such as avoiding welding and bending, preventing electrolyte leakage, and keeping away from organic solvents and corrosive environments—significantly improve the success rate of system integration and extend its service life.

Long-Term Protection, Safety First

    The sensor is designed with durability and safety in mind. A waterproof and breathable membrane protects the sensing unit, preventing clogging and contamination. Clear guidance is provided for storage and use, such as storing with the electrodes disconnected and avoiding high-concentration acidic gas environments, further ensuring the product's stable performance over long-term use.

    Whether for industrial safety monitoring or improving air quality in medical and residential environments, the MQ-E2-O2 oxygen sensor provides a reliable oxygen monitoring solution for various application scenarios with its high accuracy, fast response, and strong stability. Choosing the MQ-E2-O2 is not just choosing a sensor, but choosing a commitment to continuous safety, health, and quality. Please feel free to contact us if you have further needs:
