Ethylene oxide (ETO) is widely used in modern medical sterilization and petrochemical production due to its excellent penetrating power and sterilization effect. However, its flammability, explosiveness, and extremely high biotoxicity have also made it a key target for environmental monitoring. How can we achieve accurate early warning at low concentrations? Today, we recommend a powerful detection tool designed specifically for harsh working conditions—MQ-E3-ETO electrochemical ETO sensor.

MQ-E3-ETO Electrochemical ETO Sensor

    Technical Analysis: Millimeter-Level Precision from Potentiometric Electrolysis

    MQ-E3-ETO employs an advanced potentiometric electrolysis principle, generating current through the redox reaction of the target gas on the working and counter electrodes.

    Extremely High Sensitivity and Resolution: The sensor's measurement range is designed for 0-20ppm (maximum measurement limit up to 100ppm), with a resolution as high as 0.1ppm. This means that even minute leaks can be detected rapidly at an early stage.

    Excellent Linearity and Stability: Operating at a 300mV bias, the sensor exhibits excellent linear output characteristics and repeatability (<2% of output value), ensuring long-term reliability of monitoring data.

    Low Power Consumption: As an electrochemical component, its operating power consumption is extremely low, making it ideal for integration into portable detectors or wireless IoT monitoring terminals.

    Industry Applications: Safeguarding the Entire Lifecycle

    1. Medical Device Sterilization Station

    In the ethylene oxide sterilization process before medical devices leave the warehouse, monitoring the concentration of ethylene oxide in the workshop and exhaust system is crucial. MQ-E3-ETO can monitor ambient ETO concentration in real time, preventing occupational health hazards to workers from residual gases.

    2. Oil, Petrochemical, and Pharmaceutical Production

    Ethylene oxide, a crucial chemical intermediate, is highly susceptible to hazards during its synthesis. This sensor, with its strong anti-interference capabilities, can pinpoint the target gas within complex chemical background airflows, establishing a solid first line of defense for safety.

    3. Warehousing and Environmental Monitoring

    For temperature-controlled desorption warehouses storing sterilized items, MQ-E3-ETO sensor can be integrated with automated ventilation systems. When the detected ETO concentration exceeds a safety threshold, ventilation is automatically activated, achieving intelligent environmental management.

    Technical Specifications Overview

    MQ-E3-ETO ethylene oxide sensor, with its high accuracy and stability, fills the gap in the precise monitoring of toxic gases in industrial production. Choosing it means adding a sensitive and reliable "sensory nerve" to your safe production system.
