Carbon monoxide alarm detector with digital display, CO alarm detector with test/silencer and CO peak memory, powered by replaceable AAA battery

The carbon monoxide detector is equipped with a high-precision and reliable electrochemical CO sensor, which can quickly detect CO gas leaks to ensure safety.

The digital LCD screen displays the real-time concentration of carbon monoxide in the air (ppm). When there is no carbon monoxide in the ambient air, the screen turns off to save energy, and the green LED flashes to warn the user that its function is normal.

The carbon monoxide alarm detector has a self-test function. In normal standby mode, it automatically detects hardware faults such as internal circuits and carbon monoxide sensors to ensure the detector is always functioning properly.

Powered by 3 AAA 1.5V batteries (batteries not included). The low battery warning reminds users to replace the batteries, providing comprehensive protection.

Mounts easily on a wall or ceiling in just a few minutes using the mounting accessories.
