• Combined 5-in-1 Detector: This device is connected to a power outlet (110V - 240V), is immediately operational and constantly monitors the content of carbon monoxide (CO), smoke and fuel gas, etc.
• High Performance Long Service Life: This unit uses the principles of electrochemical reaction and resistance variation of semiconductors to quickly and accurately detect carbon monoxide, fumes and gaseous fuels. The sensor of the device is very powerful and has a long service life of about five years.
• Real-time Proximity Detection: The device is able to detect co, smoke and gaseous fuel more frequently and faster than traditional co, smoke and gaseous fuel detectors, as the sensors it contains operate every two seconds. If the device detects smoke, gas or carbon monoxide at concentrations above 50 ppm, it immediately sounds a loud alarm.
• Multifunctional: The device is also equipped with temperature and humidity sensors. It can accurately measure air temperature and humidity and display the corresponding measurements on the screen.
• Built-in Rechargeable Lithium Battery: The device comes with a built-in 2000 Mah rechargeable lithium battery that serves as a backup power supply. If the device is plugged into a power outlet and a sudden power failure occurs, the device automatically switches to power via the built-in battery.
