Multifunctional Portable 3-in-1 Carbon Dioxide Detector with Temperature & Humidity Meter and LCD Display
This intelligent carbon monoxide detector provides reliable protection for your home or workplace against dangerous CO leaks. Thanks to its precise sensing technology, it continuously monitors carbon monoxide levels in the air while also displaying temperature and humidity values.
The large, easy-to-read digital display shows real-time data, while the multi-level alarm system immediately alerts you to danger through audible and visual signals.
The device divides CO₂ detection concentration into three levels:
- Normal green level: 400–700 ppm
- Warning yellow level: 700–1500 ppm
- Dangerous red level: 1500–5000 ppm
An alarm will be triggered when the CO₂ concentration exceeds the safe range (e.g. 1500 ppm), warning you of current air quality issues.
The unit features a large LCD screen and a built-in rechargeable battery, which provides up to 40 hours of operation on a full charge.
