Ethylene is a core raw material in the chemical industry and also a key air pollutant subject to strict control. It is widely present in petrochemical, rubber and plastic production, and waste gas emission scenarios. Tensensor's MQ-E3-C₂H₄ electrochemical ethylene sensor is designed for both industrial and environmental protection scenarios and is the preferred device for ethylene gas detection.

MQ-E3-C2H4 Electrochemical Ethylene Sensor

    Core Product Advantages

    (I) Excellent Performance Parameters, Precise and Efficient Detection

    Wide Measuring Range: Standard range 0~100ppm, maximum measurement limit 200ppm, covering the full concentration range for routine monitoring and leak investigation;

    High Detection Accuracy: Sensitivity (0.070±0.015)μA/ppm, resolution 0.5ppm, capable of capturing trace amounts of ethylene, eliminating missed detections;

    Fast Response Speed: T90 response time <20 seconds, real-time feedback of concentration changes, meeting emergency early warning needs;

    Linear and Stable Output: Linear output throughout the entire range, repeatability <2%, monthly stability <5%, with no significant deviation in long-term monitoring data. 

    (II) Strong Environmental Adaptability, Suitable for Complex Working Conditions

    Wide Temperature and Humidity Tolerance Range: Operating temperature -20℃~50℃, humidity 15%~90% RH; zero drift of only 10ppm in the -20℃~40℃ range, stable operation in high and low temperature and humid environments;

    Good Pressure Compatibility: Supports standard atmospheric pressure ±10%, suitable for indoor factory areas, outdoor monitoring stations, and other environments.

    (III) Outstanding Anti-interference Capability, Reduced False Alarm Rate

    Industrial sites often involve multiple mixed gases. This sensor exhibits excellent anti-interference performance:

    No response to 100ppm hydrogen sulfide and 20ppm sulfur dioxide, completely unaffected by interference;

    Extremely low response to interference from gases such as nitric oxide and nitrogen dioxide, effectively distinguishing target gases, suitable for chemical plants and waste gas treatment sites where multiple gases coexist.

    Main Applicable Scenarios

    Industrial Scenarios: Petrochemical, coal chemical, and rubber and plastic manufacturing workshops; fixed gas alarms, portable inspection instruments, and pipeline leak monitoring equipment.

    Environmental Scenarios: Atmospheric environment monitoring stations, online monitoring systems for enterprise waste gas emissions, and regional pollution source investigation equipment.

    MQ-E3-C₂H₄ ethylene sensor boasts five key features: high precision, fast response, strong stability, strong anti-interference capability, and long lifespan, perfectly matching the core needs of industrial safety production and environmental gas monitoring. In today's trend towards intelligent and refined monitoring, this product effectively strengthens industrial safety defenses and facilitates environmental compliance control, representing a cost-effective solution for ethylene gas detection.
