FAQ

Q1: What is the primary function of a nitrogen dioxide gas sensor? ❯

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.

Q2: What detection principle do nitrogen dioxide sensors employ? ❯

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.

Q3: Do nitrogen dioxide gas sensors require regular calibration? ❯

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.
