Nitrogen oxide gas alarm

Nitrogen oxide gas alarms detect the concentration of nitrogen oxides in the air through electrochemical sensors and emit audible and visual alarms when the concentration exceeds the set threshold. They are used in places such as chemical plants and printing facilities where there is a risk of nitrogen oxide leakage to ensure personnel safety.
Selection
Confirm the type and range of the gas to be detected during selection, check the sensor lifespan and calibration cycle, consider whether the explosion-proof and protection ratings are suitable for the environment, verify the alarm method and output signal type, and inspect the product certification qualifications and after-sales service support.
