FAQ

Nitrogen oxide gas sensors detect NO concentrations in the air and are commonly used in industrial emissions monitoring, laboratory research, and environmental surveillance. Since NO is a toxic gas that readily reacts with oxygen in the air to form nitrogen dioxide (NO₂), these sensors help users promptly identify leaks and exceedances, ensuring safety and compliance.

Most NO sensors currently employ electrochemical principles, where gas diffusion triggers electrode reactions that generate current signals proportional to concentration. Additionally, optical and infrared methods are available for applications requiring high sensitivity or extended lifespan.

Generally, gas sensors require regular calibration to ensure measurement accuracy, particularly in industrial settings. Keep sensor surfaces clean and avoid prolonged exposure to high concentrations of corrosive gases. Additionally, replace electrochemical sensor elements according to product specifications to ensure long-term stable operation.
