Protect your home with this advanced 3-in-1 safety device that combines carbon monoxide detection, environmental monitoring, and emergency lighting. The sensitive CO sensor triggers an audible alarm at dangerous levels, alerting you to potentially life-threatening gas leaks before they become critical. Beyond gas detection, this portable meter simultaneously tracks temperature and humidity, helping you maintain optimal indoor air quality. The integrated flashlight provides convenient illumination during inspections or emergencies. Compact and user-friendly, it's an essential addition to any household safety kit, offering comprehensive protection for you and your family.
Safeguard your indoor environment with this precision 3-in-1 carbon monoxide detector engineered for comprehensive home safety. Featuring a rapid 35-second warm-up time and 2-second refresh intervals, the device continuously monitors CO levels across a 0–1000 ppm range with color-coded alerts: green (safe), yellow (warning), orange (dangerous), and red (high risk) with an audible alarm. The full-color LCD simultaneously tracks temperature (-10°C to 55°C) and humidity (0–100% RH), providing real-time environmental data at a glance. A high-decibel siren ensures immediate notification of hazardous conditions, while the integrated flashlight (≥100 lumens) offers practical illumination. Ideal for bedrooms, kitchens, and living spaces, this portable meter delivers professional-grade detection with user-friendly operation and reliable protection against silent but deadly carbon monoxide exposure.
