Product never used, packaging damaged during transport. Unopened product, repackaged in our warehouses, in perfect working condition, warranty available.The detector uses an advanced electrochemical carbon monoxide sensor to accurately detect carbon monoxide levels, regardless of its location in the room. Despite its small size, it offers excellent preservation. Features: Excessive Carbon Monoxide Alarm: Using coal stoves for heating and cooking in enclosed rooms, with closed doors and windows and no adequate ventilation for insufficient oxygen supply, can produce large amounts of carbon monoxide and cause indoor poisoning. LCD Display Shows CO Concentration: The number clearly indicates the gas concentration to identify the leak. Low Battery Warning: When the power drops to 3V, the buzzer will flash red every 20 seconds. After 15 alarm sequences, the device shuts down. Powerful audible and visual alarm: 85 dB precision alarm to prevent accidents. Alarm standard: The alert duration depends on the carbon monoxide concentration level. 50 ppm: alert within 60 to 90 minutes; 100 ppm: alert within 10 to 40 minutes; 300 ppm: alert within 3 minutes. (Note: When testing the detector, please do not use gas directly in the hole.)
