In industrial production and environmental protection, real-time and accurate monitoring of ozone (O₃) is crucial. Ozone is both a highly effective disinfectant and oxidant, and a potential air pollutant; excessive exposure can harm human health and the ecological environment. Tensensor's MQ-E3-O3 ozone gas sensor, with its advanced constant-potential electrolysis technology, excellent stability, and wide applicability, has become a reliable core component in industrial safety and environmental monitoring systems.

MQ-E3-O3 Electrochemical O3 Sensor

    Advanced Technology and Superior Performance

    The MQ-E3-O3 employs a constant-potential electrolytic sensing principle. Through precise circuitry, it controls the potential of the working electrode and reference electrode, causing a specific electrochemical reaction in ozone. The resulting current signal is strictly proportional to the gas concentration. This design ensures high linearity and reliability in measurement, conforming to Faraday's law and providing users with a precise foundation for quantitative analysis.

    Key Performance Highlights:

    Wide Measurement Range: 0–20 ppm (maximum measurement limit 100 ppm), covering a wide range of needs from environmental background values to industrial leak monitoring.

    High Sensitivity and Resolution: Sensitivity reaches (0.60±0.15) μA/ppm, resolution 0.02 ppm, enabling keen detection of low-concentration ozone changes.

    Fast Response: T90 response time ≤120 seconds, facilitating real-time monitoring and rapid early warning.

    Superior Stability: Monthly output stability <2%, repeatability <5%, ensuring reliable long-term monitoring data.

    Strong environmental adaptability: Operating temperature -20℃～50℃, humidity 15%～90%RH, suitable for most industrial and outdoor environments.

Multiple advantages, wide applicability

    This sensor features low power consumption, high precision, and strong anti-interference capabilities. Its compact structure and easy installation allow for easy integration into various fixed or portable detection devices. Its excellent repeatability and long-term stability significantly reduce calibration and maintenance frequency and operating costs.

    Main application scenarios include:

    Industrial process control: such as ozone generator outlet concentration monitoring, water treatment disinfection process control, and ensuring disinfection concentration in food processing plants.

    Ambient air quality monitoring: used in environmental protection fields such as urban air quality monitoring stations, industrial park boundary monitoring, and indoor air quality assessment.

    Safety leak detection: installed in ozone storage and usage sites to achieve early leak alarms and ensure personnel safety.

    Scientific research and laboratory analysis: providing a stable and accurate ozone concentration measurement tool.

    The MQ-E3-O3 ozone gas sensor, with its accurate measurement, stable output, strong environmental adaptability, and excellent anti-interference capabilities, has become an ideal choice for industrial process monitoring, environmental monitoring, and safety protection. Whether integrated into online monitoring systems or used in portable testing instruments, it provides users with continuous and reliable ozone concentration data, contributing to a safer production environment and a cleaner ecological environment.
