CO gas alarm

CO gas alarms use electrochemical sensors to detect the concentration of carbon monoxide in the air. When the concentration exceeds the set threshold, they emit audible and visual alarms. They are used in homes and industrial settings to prevent carbon monoxide poisoning accidents and ensure personnel safety.
Selection
When selecting, ensure the detection range covers 0-1000 ppm and includes a sensor lifespan reminder function. Choose between fixed or portable models based on the usage scenario. Fixed models should have relay output to support ventilation linkage. Check explosion-proof certifications and calibration cycles to ensure long-term stable operation.
