This NO gas sensor is suitable for industrial production plants, media mine shafts and alleys, environmental pollution emissions, industrial exhaust gas detection, instrumentation, storage of fuel plant warehouses, chemical plant production environment monitoring.
Tips: Can the NO gas sensor detect nitrogen dioxide (NO₂) as well?
No, this NO sensor is specifically designed for nitric oxide (NO) detection. While some cross-sensitivity to NO₂ may exist, a dedicated NO₂ sensor should be used for accurate nitrogen dioxide monitoring. If both gases need to be measured, a dual-sensor system can be used to differentiate between NO and NO₂ concentrations.
