NOX Alarm

NOX alarms detect nitrogen oxide concentrations in the air through electrochemical sensors and emit audible and visual alarms when levels exceed standards. They are used for industrial exhaust monitoring and workshop safety protection to prevent health hazards caused by nitrogen oxide accumulation.
Selection
When selecting, ensure the detection range covers the actual concentration, and that it has explosion-proof certification and calibration functions. Consider the sensor's lifespan and response speed, and ensure the environmental temperature and humidity match the usage scenario. Perform regular maintenance to ensure data accuracy.
