• 【Detecting Carbon Monoxide Gas】Using electrochemical sensor technology, this CO detector provides precise detection of CO gas. It is equipped with a built-in test button and a low battery warning, ensuring that you can sleep soundly knowing your CO detector is functioning optimally. It is widely used in homes, kitchens, garages, travel trailers, RVs, food trucks, restaurants, hotels, and more. This CO detector helps reduce the risk of injury from gas leaks, protecting you and your family
• 【Battery-Powered CO Detector】This easy-to-install CO detector is powered by 3 * 1.5V AA batteries (not included). The system requires a warm-up time of approximately 2 minutes. During this time, the CO monitor will not function. Wait for the display to show “0” (indicating the system is operational) before performing tests. Unlike most CO detectors, this unit can be mounted on the wall or placed independently on a table
• 【Powerful Quality and Features】The CO alarm uses a high-quality 5-year electrochemical sensor, ensuring more accurate response times to CO gas exposure and reducing the risk of false alarms. The LED display shows the CO concentration, and a low-battery alarm alerts you when it’s time to replace the batteries
• 【Visual and Audible CO Alerts】Upon detecting carbon monoxide, the alarm emits an 85-decibel sound. Alarm thresholds are as follows: 50ppm: Delayed 100 minutes (within 2 hours) alarm. 100ppm: Delayed 75 minutes (within 1 hour) alarm. 300ppm: Delayed 20 minutes alarm. Above 300ppm: Alarm within 3 minutes.When the CO concentration drops to 30ppm, the screen will turn off and the detector will return to normal monitoring mode
• 【Prioritize Safety】Unchecked carbon monoxide leaks in sleeping areas can cause illness or worse. This battery-powered CO detector immediately alerts you when an issue arises, allowing you to respond promptly and resolve any potential problems
