In the industrial and environmental sectors, hydrogen is a clean energy source and an important chemical raw material, making its safety monitoring particularly critical. Hydrogen is colorless, odorless, flammable, and explosive; leaks can cause serious safety accidents. Therefore, reliable and accurate hydrogen detection equipment has become an industry necessity.

    Tensensor's MQ-E3-H2 hydrogen sensor is a high-efficiency detection solution designed to meet this need. This sensor utilizes advanced fuel cell principles, generating a current signal proportional to the hydrogen concentration through the redox reaction of hydrogen and oxygen at the working electrode, achieving high-precision and high-sensitivity real-time monitoring.

Key Advantages

    High Precision and Sensitivity: Sensitivity reaches (0.010±0.005) μA/ppm, with a resolution as low as 2ppm, ensuring accurate response even in low-concentration environments.

    Wide Temperature and Humidity Adaptability: Operating temperature range -20℃～50℃, humidity range 15%～90% RH, adaptable to various harsh industrial environments.

    Excellent Anti-interference Capability: Extremely low cross-interference, with weak response to common interfering gases such as hydrogen sulfide, carbon monoxide, and ethylene, ensuring reliable and accurate detection results.

    Long Lifespan and Stability: Lifespan up to 2 years, monthly output stability better than 2%, repeatability <2%, suitable for long-term continuous monitoring.

Wide Range of Applications

    MQ-E3-H2 sensor is suitable for various scenarios including the hydrogen energy industry chain, chemical plants, hydrogen storage stations, environmental monitoring stations, and laboratories. It can be embedded in fixed or portable detection equipment to achieve early warning and real-time monitoring of hydrogen leaks.

Intelligent Protection, Worry-Free Safety

    This sensor not only boasts excellent performance indicators but also prioritizes practicality and safety in its design. It features a compact structure, low power consumption, fast response (T90 ≤ 90 seconds), and excellent linear output characteristics, facilitating system integration and data analysis.

    In today's world, where safe production and green development are increasingly emphasized, the MQ-E3-H2 hydrogen sensor, with its reliable performance and stable operation, has become a "smart sentinel" for hydrogen monitoring in industrial and environmental fields. Choosing the MQ-E3-H2 means choosing continuous safety assurance and accurate data support.
