Description The portable carbon monoxide detector for travel is easy to install, easy to use and easy to carry. The carbon monoxide detector is built-in advanced electrochemical CO sensor that provides high-precision alarms for fast and accurate detection of carbon monoxide levels. When the carbon monoxide concentration exceeds the specified value, an alarm warning of more than 85 decibels will be issued. To complete protection, be to place one on floor of your home and in bedroom. The carbon monoxide detector is suitable for all where carbon monoxide may be produced, such as your home kitchen, bedroom, bathroom, warehouse, hotel, car, parking lot or barbecue time The portable carbon monoxide detector is powered by 2*1.5V AAA batteries (not included), which is easy to use, just one test/reset button. The carbon monoxide detector has an LCD digital display that displays real-time CO levels, allowing you to see any significant changes in CO levels, and can display battery life, prompting you to replace batteries.The intuitive LED indicator can clearly inform the working status of the CO alarm detector: the green LED indicates normal operation, the red LED indicates the alarm status, and the yellow LED indicates the fault. The carbon monoxide detector is easy to install without rewiring. It can be mounted on any wall or ceiling, as as in a car.
