The presence of chlorine near chemical reactors, in pharmaceutical workshop ventilation shafts, and at wastewater treatment plant monitoring points is a double-edged sword. Effective monitoring of this critical industrial gas requires precise, stable, and reliable technological solutions. MQ-E3-Cl2 constant-potential electrolysis chlorine sensor is designed precisely for this purpose.

    Precise Monitoring Based on Mature Principles

    MQ-E3-Cl2 sensor employs a long-proven constant-potential electrolysis method. Its working principle is direct and reliable: when chlorine diffuses into the sensor, a specific electrochemical reaction occurs on the surface of the working electrode, generating a micro-current strictly proportional to the gas concentration. By accurately measuring this current signal, the real-time concentration of chlorine in the environment can be accurately calculated.

    This method does not rely on complex inferences or indirect calculations; its results are directly derived from fundamental electrochemical laws, ensuring the objectivity and traceability of the monitoring data.

    Core Features Designed for Industrial Sites

    Industrial environments place clear demands on monitoring equipment: accuracy, stability, and durability. MQ-E3-Cl2 sensor addresses these needs in several ways:

    High Precision and Fast Response: The sensor maintains high sensitivity to chlorine, accurately capturing early signs of low-concentration leaks and providing a valuable data window for timely intervention.

    Selective Interference Resistance: Optimized to reduce cross-interference risks and ensure accurate alarm readings, the sensor is designed to handle interfering gases such as ozone and nitrogen dioxide in industrial environments.

    Long-Term Operational Stability: Through material optimization and process control, the sensor maintains stable signals during long-term continuous operation, reducing calibration frequency and maintenance costs.

    Wide Linear Range and Low Power Consumption: Suitable for various concentration scenarios from safety monitoring to process control, its low power consumption meets the needs of both fixed installations and portable mobile monitoring.

    Focusing on Key Application Areas

    The sensor's design is consistently centered around practical applications:

    Chemical Safety Production: Continuously monitoring potential leaks in pipelines, valves, and storage tank areas.

    Pharmaceutical Manufacturing Environment: Ensuring environmental safety and compliance in workshops involving chlorine processes.

    Environmental Monitoring Network: Used for boundary emission monitoring and ambient air quality assessment.

    Public Facility Safety: Suitable for risk management in water treatment plants, laboratories, and other similar locations.
