    FAQ
    ❯

    Nitrogen dioxide gas sensors detect the concentration of NO₂ in the air. NO₂ is a common atmospheric pollutant primarily originating from combustion emissions and industrial production. Prolonged inhalation can harm the respiratory system, necessitating real-time monitoring.

    ❯

    Common NO₂ sensors employ either electrochemical or optical principles. Electrochemical sensors offer high sensitivity and fast response, making them suitable for portable devices. Optical detection provides excellent stability, ideal for fixed, long-term monitoring.

    ❯

    Yes. To maintain accuracy, calibration is recommended every 6-12 months based on the operating environment. For harsh conditions or critical monitoring points, calibration intervals should be shorter.
