In the realms of traffic enforcement, workplace safety, and personal health management, the precise detection of alcohol concentration constitutes not merely a technical challenge, but a critical line of defense for safeguarding human life. Leveraging cutting-edge fuel cell electrochemical technology, Tensensor's MQ-E2-C₂H₅OH-φ16 alcohol sensor offers the industry a "gold standard" solution that combines exceptional sensitivity with outstanding stability.

MQ-E2-C2H5OH Electrochemical Alcohol Sensor

    Technical Core: The Generational Advantage of Fuel Cell Principles

    The MQ-E2 series employs high-performance fuel cell-based electrochemical sensing technology. Unlike traditional semiconductor alcohol sensors, it generates a direct electrical signal through the redox reaction of alcohol occurring at the working electrode:

    Precise Translation of Faraday's Law: The magnitude of the electrical current maintains a strictly proportional relationship with the alcohol concentration. Within the measurement range of 0 to 1.0 mg/L, the sensor demonstrates exceptional linearity, ensuring consistent readings across the entire spectrum—from trace amounts to high concentrations.

    Lightning-Fast Response: Every Second Counts: The response time (T90) is less than 20 seconds. In scenarios requiring rapid screening—such as traffic enforcement patrols or pre-shift checks for high-altitude operations—this capability for immediate feedback significantly boosts detection efficiency.

    Low Power Consumption and High Stability: As an electrochemical sensor, it consumes extremely low power, making it ideally suited for integration into portable, battery-powered sampling devices. Furthermore, with a monthly stability drift of less than 2%, the device's calibration cycle is significantly extended.

    Key Highlights: Why Is It the Preferred Choice for Professional Applications?

    An "Interference Filter": It possesses a robust ability to distinguish between alcohol and common interfering gases present in the environment. This effectively minimizes false alarms caused by environmental impurities, allowing the sensor to target alcohol molecules with pinpoint accuracy.

    Miniaturized Design: Featuring a compact structure with a diameter of just 16mm—and paired with a standard analog current output—the sensor allows device designers to effortlessly embed it into a wide variety of handheld or wearable detection terminals.

    Wide Temperature Adaptability: It operates stably across a broad temperature range of -20°C to 50°C. Additionally, it boasts excellent zero-point drift control capabilities (within -0.01 mV to +0.01 mV), ensuring reliable detection results regardless of whether the conditions are bitterly cold or scorching hot.

    MQ-E2-C₂H₅OH-φ16 Alcohol Sensor is more than just a sensor; it represents Tensensor's profound embodiment of the philosophy of "Professionalism, Precision, and Purity." For manufacturers of safety equipment who strive for the utmost precision and reliability, this module serves as the pivotal catalyst propelling your products into the professional-grade market.
