Smart 3-Stage Alert System: Featuring an intuitive smart alert system, it uses distinct colored lights and sounds to indicate danger levels: steady green for safe, low levels; flashing yellow with low-frequency beep and vibration from 50 PPM (warning); and rapid red flashing with high-frequency alarm and stronger vibration at 100+ PPM (danger), ensuring you're alerted promptly in any environment.

Long Battery Life & Convenient Charging: Powered by a 1100mAh rechargeable battery, it supports up to 7 days (168 hours) of continuous monitoring on a single charge. The universal Type-C port allows for fast and convenient recharging. A smart low-battery alert beeps every 2 minutes below 20% charge, reminding you to recharge before power runs out.

High Accuracy & Fast Response: Equipped with a high-performance electrochemical sensor, it updates readings every second for fast response to changing CO levels. The sensor is built to last up to 5 years, delivering stable and reliable monitoring performance to help you stay ahead of potential risks.

Compact, Portable & Flexible Mounting: Compact and lightweight (approx. 3.15” x 2.36” x 1.02”, 0.19 lb) for easy portability. The magnetic back attaches firmly to metal surfaces, and the built-in lanyard hole allows for hanging on backpacks, in tents, or vehicles.
