Plug-in 5-in-1 Combo Smoke and Carbon Monoxide Detector Gas Detector with 1000mAh Battery & HD Screen [Smoke, Temperature, Humidity Alarm] for Family and Travel, White, HD13-CGS White -

High performance and long lifespan: This device uses the principles of electrochemical reaction, semiconductors, and the photoelectric effect to quickly and accurately detect carbon monoxide, combustion gases, and smoke. The sensors in this device offer high performance and a long lifespan of approximately 5 years. Large color LCD screen: This device provides real-time approximate measurements, and all measurement values are displayed simultaneously on a high-resolution 2.45-inch color LCD screen. The large LCD screen makes measurement values highly visible and easy to read. Combined smoke, combustion gases, and CO: By connecting this device to a household electrical outlet, it can continuously monitor the levels of smoke, carbon monoxide (CO), and combustion gases such as natural gas, liquefied natural gas (LNG), liquefied petroleum gas (LPG), methane (CH4), ethane (C2H6), propane (C3H8), butane (C4H10), etc. Compliant with EU safety standards: This device complies with European Union safety standards and has the corresponding test standards for CO indicators (EN 50291), gas indicators (EN 50194), and smoke indicators (EN 14604). It offers high reliability and stable performance. Approximate real-time detection: Compared to traditional CO and gas indicators, this device can detect carbon monoxide and combustion gases much more frequently and quickly, as its sensors operate every 2 seconds. As soon as this device detects combustion gases or carbon monoxide at a concentration above 50 ppm, a loud audible alarm is immediately emitted. Built-in rechargeable lithium battery: This device has a built-in 1000 mAh rechargeable lithium battery as an emergency power source. If the device is connected to a power outlet and a sudden power outage occurs, the device automatically switches to mains power via the built-in battery. The built-in battery can power the device for approximately 10 hours after a full charge.
