Nitrogen Dioxide Detection Alarm

The nitrogen dioxide detection alarm operates by using an electrochemical sensor that reacts with the gas to generate an electrical current signal. When the concentration exceeds the preset threshold, it triggers audible and visual alarms. It is used to monitor harmful gas leaks in processes such as ink drying in printing factories and plastic pyrolysis, ensuring personnel safety.
Selection
When selecting, ensure the detection range covers 0-50 ppm, includes explosion-proof certification, and data logging functionality. The sensor lifespan is approximately 2 years, with priority given to devices equipped with a self-test mode. The installation location should avoid ventilation openings, and regular calibration with standard gas is required.
