Description
This 4-in-1 carbon monoxide alarm detector is a reliable safety tool designed for homes and small enclosed spaces. Equipped with professional-grade, high-precision sensors, it supports real-time monitoring of four environmental parameters. Combined with a high-brightness LCD screen that displays data clearly, it keeps you informed of safety conditions at all times.
Key Features
Sturdiness and Longevity: Made from premium plastic, this product boasts hardness against scratches and impacts, ensuring enduring performance and is safe to use.
4-in-1 Powerful Detection: This device integrates four core monitoring functions—methane, carbon monoxide, temperature, and humidity—enabling a single unit to meet the needs of household gas leak detection, carbon monoxide poisoning risk alerts, and environmental temperature and humidity monitoring
Enhanced Safety: It is equipped with high-precision sensors, and it provides 360° all-around detection and is highly sensitive to changes in methane and carbon monoxide concentrations. Once concentrations exceed the threshold, a high-decibel audible and visual alarm is immediately triggered, effectively waking users even from deep sleep to prevent poisoning or explosion accidents.
Easy to Use: Featuring a plug-in design that supports a wide AC voltage range of 110–240V, it does not require batteries or additional wiring. Simply plug it into an electrical outlet to use. Equipped with a one-touch test button, allowing users to easily verify device functionality. Its user-friendly design makes it simple for the elderly and children to use, significantly reducing installation and maintenance costs.
Clear and Intuitive Display: It features a high-brightness LCD digital display that shows real-time temperature (switchable between °C and °F), humidity, carbon monoxide concentration (PPM), and methane concentration (% LEL). Green, red, and yellow indicator lights represent power status, alarms, and malfunctions, respectively, allowing users to quickly assess environmental safety conditions.
Details
Round Edges: Smooth edges not only feel comfortable to the touch but also enhance safety during use.
Modern Black Hue: The black exterior looks stylish and sleek.
