Features

4-in-1 Gas & CO Safety Monitoring：This 4-in-1 safety detector monitors Carbon Monoxide (CO), combustible gas (Natural Gas, Methane, Propane), temperature, and humidity in real time. It helps identify invisible gas hazards early and provides continuous environmental awareness.
Important: This device is designed specifically for CO and gas detection. It does not detect smoke or fire and should be used together with existing smoke alarms for complete home protection.

Plug-in Design with 1000mAh Battery Backup: Designed for simple plug-and-play installation, the detector connects directly to a wall outlet for 24/7 continuous monitoring. A built-in 1000mAh rechargeable backup battery keeps the alarm active during temporary power outages, ensuring your safety protection continues even when electricity is interrupted.

Triple Alarm System with Powerful 85dB Alert: When dangerous gas or CO levels are detected, the detector activates a triple alarm system including a loud 85dB siren, flashing warning light, and clear on-screen alert, helping notify occupants immediately so they can react quickly and evacuate safely.

LCD Display with Adjustable Brightness: The large LCD display clearly shows CO concentration, gas status, temperature, and humidity in real time, making safety information easy to read at a glance. With 3-level adjustable brightness (0% / 50% / 100%), you can dim or completely turn off the backlight at night for comfortable sleep while monitoring continues.

Recommended Installation & Usage Areas: Ideal for areas where gas appliances are commonly used, including kitchens, garages, boiler rooms, RVs, and utility areas. The plug-in wall design should be installed in standard outlets rather than ceilings. For best sensor performance, avoid placing the detector in bathrooms or directly above cooking stoves.
