Battery-operated carbon monoxide detector with sensitive sensor, digital display and audible alarm for use in hotels and homes, 1 piece

【High Reliability, 24/7 Protection】: Carbon monoxide detectors use advanced electrochemical sensors and CO detection chips to quickly identify invisible, odorless, and deadly carbon monoxide in your home, ensuring your family's safety around the clock. 【Multi-Level Smart Alarms】: Anticipate danger with standard CO detector alerts: 50 ppm (alerts within 60-90 minutes), 100 ppm (within 10-40 minutes), and 300 ppm and above (in just 3 minutes), giving you valuable reaction time. 【Clear and Intuitive Design】: An easy-to-read screen displays real-time CO levels, while a tri-color LED provides instant updates: green for normal operation of the carbon monoxide alarm (flashes every 30 seconds), yellow for a fault, and red for danger. The peak memory function alerts you to leaks you might have missed while you were away. 【Convenient Installation】: Simply mount the battery-operated carbon monoxide detector on the wall or ceiling (hardware included) and power it with 2 AA batteries (included). The CO detector requires no power outlet, ensuring continuous monitoring even during a power outage. 【Widely Used】: Suitable for various environments where carbon monoxide may be present, such as your kitchen, bedroom, bathroom, hotel, or during outdoor activities like barbecues or parking lots. Our carbon monoxide detectors offer reliable and affordable protection.
