Accurate ozone monitoring is crucial in industrial production and environmental protection. Ozone is both a highly efficient oxidant and a potentially harmful gas, and its real-time concentration control directly impacts production safety, equipment protection, and personnel health. Tensensor's MQ-E3-O3 ozone gas sensor, with its constant potential electrolysis technology and superior detection performance, is the ideal choice for industrial-grade ozone monitoring.

MQ-E3-O3 Electrochemical O3 Sensor

Core Technological Advantages: Stable, Accurate, and Reliable

    The MQ-E3-O3 sensor employs a constant-potential electrolysis method, achieving highly selective oxidation of ozone through precise control of the working electrode potential. The generated current signal is strictly proportional to the ozone concentration. Combined with a built-in load resistor and optimized circuit design, this ensures high linearity and low noise interference in the detection process.

    The sensor possesses the following outstanding characteristics:

    High Sensitivity and Wide Measurement Range: Detection range covers 0–20ppm, with a maximum measurement limit of 100ppm. Sensitivity reaches (0.60 ± 0.15) μA/ppm, and resolution is as fine as 0.02ppm, meeting diverse needs from environmental monitoring to industrial process control.

    Excellent Environmental Adaptability: Operating temperature range -20℃ ~ 50℃, humidity adaptability 15% ~ 90%RH (non-condensing), with excellent temperature drift suppression capability and zero-point drift ≤ 0.2ppm, ensuring data stability in complex industrial environments.

    Strong anti-interference capability: After systematic cross-interference testing, the sensor exhibits extremely low cross-interference response to various common industrial gases such as carbon monoxide, sulfur dioxide, and hydrogen sulfide, significantly improving the reliability of monitoring data.

    Long lifespan and low maintenance: The sensor has a lifespan of up to 2 years in normal air environments, with monthly stability < 2% and repeatability error < 5%, significantly reducing the frequency of system calibration and replacement.

Wide Range of Industrial Applications

    This sensor is suitable for various ozone-related industrial scenarios, including but not limited to:

    Ozone Generator Monitoring: Used for real-time feedback and control of ozone production concentration in systems such as water treatment, air purification, and food disinfection.

    Industrial Process Control: Monitors ozone dosage in processes such as chemical synthesis, pulp bleaching, and wastewater treatment to optimize reaction efficiency.

    Environmental Safety Monitoring: Monitors ozone leakage in densely populated areas such as workshops and factories to ensure occupational health and production safety.

    Environmental Emission Monitoring: Used in conjunction with flue gas or waste gas treatment systems to achieve compliant monitoring of ozone emissions.

    Combining its advantages of high precision, strong anti-interference, wide temperature and humidity adaptability, and long service life, the MQ-E3-O3 ozone sensor is not only a detection device but also a reliable partner in industrial ozone management. For industrial users who prioritize system stability, data accuracy, and low operating costs, this sensor offers a cost-effective and technologically advanced ozone monitoring solution.

    If you are looking for an ozone sensor suitable for harsh industrial environments, the MQ-E3-O3 is undoubtedly a top choice.
