    Mini portable oxygen gas detector structureApplications

    Oxygen gas detectors find application in various fields, including industrial settings, laboratories, and confined spaces, to ensure the safety of personnel by continuously monitoring and alerting to oxygen levels, thus preventing potential hazards such as oxygen deficiency or enrichment.

    Oxygen gas detector applications
    Tips: how does Mini Portable Oxygen (O2) Gas Detector work?

    1. Sensor Technology: Portable O2 gas detectors rely on electrochemical sensors or optical sensors to measure oxygen concentrations. Electrochemical sensors are the most common type used in these devices. They work based on the electrochemical reaction that occurs when oxygen molecules interact with a chemical electrode. This reaction generates a small electrical current, which is proportional to the concentration of oxygen in the environment.

    2. Gas Detection Principle: The fundamental principle behind the operation of a portable O2 gas detector is based on the fact that the electrical current generated in the sensor is directly related to the number of oxygen molecules that come into contact with the sensor's surface. As the concentration of oxygen increases or decreases, the electrical current produced by the sensor also changes accordingly.

    3. Display and Alarming: Portable O2 gas detectors are equipped with a display that typically shows the oxygen concentration as a percentage (e.g., 20.9% for normal atmospheric oxygen levels). The detector continuously monitors the oxygen levels and displays real-time readings. When the detected oxygen level falls outside the pre-set safe range, the device triggers an alarm, which can be visual, audible, or both, to alert the user to potential safety hazards.

    4. Safe Thresholds: These detectors are often programmed with two critical threshold levels:

    • Low Oxygen Alarm: This alarm activates when oxygen levels drop below a safe level, indicating the possibility of oxygen deficiency, which can be life-threatening in certain situations.
    • High Oxygen Alarm: This alarm triggers when oxygen levels rise above the safe range, indicating oxygen enrichment, which can also pose health and safety risks.

    5. Calibration: To ensure the accuracy of the readings, portable O2 gas detectors require periodic calibration. Calibration involves exposing the detector to a known concentration of oxygen, usually in a controlled calibration gas environment. The detector's internal settings are then adjusted to match the known concentration, ensuring that the device provides accurate readings.

    Easy to carry and operate
    This small oxygen detector is very practical. It is small and easy to carry. It has only two buttons and is easy to operate. There is also a video to teach me how to operate it. The service is very good.
