Nitrogen dioxide gas alarm

The nitrogen dioxide gas alarm detects the concentration of nitrogen dioxide in the air using an electrochemical sensor. When the concentration exceeds the preset threshold, it triggers audible and visual alarms. It is used in locations such as chemical plants and printing facilities where there is a risk of nitrogen dioxide leakage, ensuring personnel safety.
Selection
When selecting, ensure the detection range covers the concentration of the application scenario, check the sensor lifespan and calibration cycle, verify explosion-proof certification and IP protection rating, confirm support for audible and visual alarms and signal output functions, and consider installation method and environmental compatibility.
