In chemical production, pharmaceutical manufacturing, and environmental monitoring, chlorine is a common but highly hazardous gas. Leaks and excessive emissions can easily lead to safety accidents and environmental pollution. Achieving real-time, accurate, and reliable chlorine monitoring has become a crucial aspect of enterprise safety production and environmental governance. 

MQ-E3-Cl2 Electrochemical Cl2 Sensor

    Tensensor's MQ-E3-CL2 chlorine sensor was developed to solve this problem. This sensor uses a constant-potential electrolysis principle, detecting chlorine concentration in real time through an electrochemical reaction. The output current signal is proportional to the gas concentration, exhibiting high sensitivity and excellent linearity, making it an ideal choice for industrial gas monitoring.

Core Advantages, Showcasing Professional Quality

    High Precision and Wide Linear Range: Measuring range 0~10ppm, resolution up to 0.1ppm, stable linear output, suitable for precise monitoring of low concentrations and early warning of high concentrations.

    Strong Anti-interference Capability: Exhibits extremely low response to common interfering gases such as hydrogen sulfide, carbon monoxide, and sulfur dioxide, ensuring accurate and reliable monitoring results.

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

    Long-Term Stability: Output stability <2%/month, service life up to 2 years, significantly reducing maintenance frequency and operating costs.

    Safe Design: Robust structure, waterproof and breathable membrane protection, prohibits contact with soldering and organic solvents, ensuring long-term stable operation.

Wide Range of Applications, Safeguarding Multiple Safety Aspects

    Chemical Industrial Parks and Pharmaceutical Workshops: Real-time monitoring of chlorine leaks during production processes, preventing poisoning and explosion risks.

    Environmental Monitoring Stations: Used for monitoring chlorine emissions in the atmosphere, assisting in environmental pollution control.

    Wastewater treatment and disinfection: Monitors the chlorine dosing process to ensure operational safety and process stability.

    Laboratories and research institutions: Provides accurate gas concentration data to support experimental analysis and safety protection.

Intelligent protection starts with precise sensing.

    The MQ-E3-CL2 is not just a sensor, but a complete gas safety solution. Its low-power design, fast response (T90 < 60 seconds), and excellent repeatability make it easy to integrate into various gas detectors, fixed monitoring systems, and IoT security platforms, achieving end-to-end intelligent protection from "sensing" to "early warning."

    In the field of gas safety monitoring, accuracy and reliability are always the primary standards. The MQ-E3-CL2 chlorine sensor, with its superior performance, rigorous manufacturing process, and long-term stability, has become the trusted choice for many chemical and environmental protection companies and institutions.
