1. This latest 4-in-1 CO & Gas detector integrates carbon monoxide, combustible gas, temperature and humidity sensors to provide us with real-time detection of ambient gas safety.
2. US standard plug is compatible with 110V to 220V AC outlets. Works with all US standard AC outlets in bedrooms, kitchens, living rooms, basements, hotel rooms, camping and more.
3. All data is displayed in real time on the HD screen, we can read data faster from large icons such as: CO ppm, combustible gas indicator bar, humidity, temperature, CO indicator icon and alarm status.
4. Built-in UL standard independent combustible gas sensor and CO sensor, HD screen visibility and 85 dB hear design detects gas environment in real time for extra safety for you and your family. Create a complete house safety warning for you.
5. CO range: 0-2000ppm, alarm will sound when CO is >150ppm. If the combustible gas exceeds the alarm concentration, the detector will sound and the gas bar icon will change color.
