【10-Year Battery Life & Continuous Protection】 Powered by a built-in 3V non-replaceable lithium battery, this carbon monoxide alarm provides up to 10 years of reliable, uninterrupted 24/7 protection. Save money and effort by eliminating the need for frequent battery replacements over a decade.

【Smart 2-in-1 LCD Backlight Display】 In standby mode, the multi-functional LCD screen alternately displays the current indoor temperature and humidity, acting as a handy home weather monitor. Once CO is detected, it instantly switches to show precise CO concentrations with a user-friendly blue backlight for easy reading in the dark.

【Advanced Electrochemical Sensor】 Equipped with a premium electrochemical CO sensor, this detector is highly sensitive and stable, capable of measuring CO levels as low as 30 ppm. It triggers instant alarms based on strict safety thresholds (50/100/300 ppm) to guard your family against the "silent killer."

A large 2-in-1 Test/Silence button allows for quick weekly functional testing and a 9-minute temporary mute during false alerts. Thoroughly tested to meet stringent European CE safety standards.
