4-in-1 carbon monoxide detector and natural gas leakage detector, portable carbon monoxide detector with plug-in and battery backup - hotel and travel safety, RV, home

4-in-1 Upgraded Carbon Monoxide Detector The 4-in-1 multi-sensor detector integrates carbon monoxide (CO), combustible gas, temperature and humidity monitoring into a compact device. It will alert users to risks such as gas leakage, fire hazards or air quality issues, while tracking temperature and humidity to achieve overall protection. It is very suitable for family, workplace and RV travel

Easy Installation The carbon monoxide detector plug is compatible with AC power ranging from 110V to 220V. The static power consumption does not exceed 2W, it is plug-and-play and suitable for all American standard AC power sockets in bedrooms, kitchens, living rooms, basements, hotels, etc

Equipped with a 1000mAh rechargeable lithium battery, this gas detector ensures 24-hour continuous operation during power outages and provides reliable emergency backup. Unlike disposable batteries, its eco-friendly design avoids frequent replacement, reducing long-term costs while maintaining stable performance. It is highly suitable for emergency situations or unstable power environments, combining extended operating time and cost-effectiveness to achieve worry-free safety monitoring

Voice and Light Alarm Utilizing highly sensitive electrochemical sensors, it provides real-time environmental safety updates and displays the concentration of harmful gases on the high-definition screen in real time. When the concentration of carbon monoxide gas reaches the alarm level (>150ppm), the red light will continue to flash and trigger an 85dB alarm. It can detect carbon monoxide levels ranging from 0 to 999ppm, as well as LEL natural gas levels from 0 to 20%.

High-definition Real-time Display Equipped with a vivid color LCD screen, it can monitor carbon monoxide (PPM), bubbles/flammable gas (%LEL), temperature (°F), and humidity (RH%) in real time at night, ensuring rapid emergency response and achieving all-weather safety monitoring.

Tip Please remove the protective film before use. After the device is inserted, wait for 120 seconds for the calibration to complete, and then press the self-test button to activate the alarm. After unplugging the power supply, the temperature and humidity readings may experience temporary fluctuations. It will be completely accurate within 120 seconds.
