Your family’s safety should never be a guessing game. This smart carbon monoxide detector gives you instant peace of mind with a clear LCD display, powerful alarm, and reliable performance that never sleeps. It’s security you can see and trust - for a full decade.
Equipped with a high-precision electrochemical sensor, this device detects even low levels of carbon monoxide. If danger is near, a loud 85 dB alarm alerts you instantly - ensuring you’re always one step ahead of silent threats.

Forget frequent replacements. The sealed lithium battery lasts up to 10 years, giving you round-the-clock protection with no wiring, no hassle, and no extra cost. It's designed to work quietly in the background - so you don’t have to.

The LCD screen provides real-time readings of CO levels - even when everything seems normal. Thanks to its built-in backlight, you can easily check readings in dim light or at night without second-guessing your safety.

Three intuitive LED indicators keep you informed. Green means all is well, yellow signals an issue, and red alerts you to danger. No need to interpret confusing sounds - the light tells you exactly what’s happening, instantly.

Mount it on a wall, place it on a shelf, or take it with you when you travel - it’s lightweight and portable. Whether in your home, RV, hotel room, or office, this detector offers reliable protection wherever you go.

Don’t underestimate the power of something so compact. With durable ABS construction, high visibility, and a failsafe sensor, this CO alarm blends into your space while offering maximum protection - all without drawing attention.
