In industrial production and environmental protection, accurate and reliable monitoring of hydrogen is crucial. Hydrogen, as a clean energy source, is widely used in fuel cells, chemical production, and energy storage; however, its flammable and explosive properties also pose safety hazards. Therefore, selecting a stable, sensitive, and interference-resistant hydrogen sensor is key to achieving safe production and environmental monitoring.

    Tensensor's MQ-E3-H₂ hydrogen sensor is a high-performance gas detection solution designed based on fuel cell principles. With its superior technical specifications and reliable characteristics, it has become an ideal choice for hydrogen monitoring in industrial and environmental fields.

MQ-E3-H2 Electrochemical H2 Sensor

Core Technology: Fuel Cell Sensor, Accurate and Reliable Response

    The MQ-E3-H₂ employs advanced fuel cell sensing technology. Hydrogen and oxygen undergo a redox reaction at the working and counter electrodes, generating a current signal proportional to the hydrogen concentration. This technology follows Faraday's law, featuring linear output, stable response, and high sensitivity, enabling accurate quantitative analysis of hydrogen concentration.

Superior Performance: High Precision, Wide Measuring Range, Strong Anti-interference

    Wide Measuring Range: 0~1000ppm, maximum measurable 2000ppm, covering common industrial monitoring needs;

    High Sensitivity: Typical value 0.010μA/ppm, resolution up to 2ppm, capable of capturing trace hydrogen gas changes;

    Rapid Response: T₉₀ response time ≤90 seconds, timely warning, improving safety response capabilities;

    Good Stability: Repeatability <2%, monthly stability <2%, reliable even after long-term use;

    Strong Environmental Adaptability: Operating temperature -20℃~50℃, humidity 15%~90%RH, suitable for various industrial environments.

Strong Anti-interference Capability, More Reliable Data

    In complex industrial gas environments, cross-interference is a common problem for sensors. The MQ-E3-H₂, through optimized electrode structure and materials, significantly reduces the response to common interfering gases such as hydrogen sulfide, carbon monoxide, and nitrogen oxides, ensuring high selectivity and reliability of hydrogen detection data and avoiding false alarms.

    Industrial-Grade Durable Design, Long Service Life

    The sensor features a robust structural design, possessing excellent mechanical strength and environmental resistance. In normal air environments, its service life can reach 2 years, supporting long-term continuous monitoring, reducing maintenance and replacement frequency, and saving operating costs.

Wide Range of Applications

    Hydrogen leak monitoring in fuel cell systems

    Hydrogen concentration monitoring in chemical production processes

    Safety monitoring of hydrogen storage and transportation facilities

    Hydrogen emission detection in environmental protection

    Hydrogen analysis for laboratory and research use

    The MQ-E3-H₂ hydrogen sensor, with its comprehensive advantages of high precision, high stability, strong anti-interference, and long service life, provides reliable gas detection support for industrial safety and environmental protection. Choosing Tensensor means choosing peace of mind and professionalism.
