【5-in-1 Air Quality Monitor】This CO₂ monitor combines CO₂ concentration, temperature, and humidity detection into a single device. Equipped with a 2-inch high-definition color screen and an 85-decibel audible alarm, it gives you an at-a-glance view of your indoor air quality. When CO₂ levels exceed safe thresholds, the device sounds an alarm to promptly remind you to open a window for ventilation, safeguarding the respiratory health of you and your family.
【Customizable Settings, Full Control】 Operation is simple and intuitive: press the “O” button to easily switch between °C and °F temperature units; press the “H” button to adjust screen brightness or turn off the backlight to adapt to different lighting conditions. You can also briefly press the “D” button to manually turn the buzzer on or off, avoiding disturbances when you need quiet.
【Plug-and-Play, Continuous Monitoring】 Equipped with high-precision sensors, it detects CO₂ concentrations ranging from 400 to 4,000 ppm with a measurement accuracy of ±5% and a refresh rate of just two seconds, ensuring precise and reliable data. Its plug-and-play design eliminates the hassle of replacing batteries, letting you sleep soundly.
【140-Day Extended History Log】 With built-in high-capacity data storage, it can save up to 140 days of historical data. Press and hold the “H” button to enter history mode and easily review past air quality changes. In history mode, press the “D” button to view the next page, the “H” button to return to the previous page, and the “O” button to return to the main interface—making data analysis more efficient.
【10-Year Durable and Reliable Sensor】 This sensor offers exceptional durability and requires no frequent inspections or replacements once installed. It provides long-term, stable, and highly accurate air monitoring, effectively reducing maintenance costs and delivering up to 10 years of reliable, worry-free use.
【The Importance of Air Quality Monitoring】 Low concentrations of carbon dioxide are generally harmless, but when levels exceed certain thresholds, they can affect the breathing of humans and other living organisms. In severe cases, it can even be life-threatening. Therefore, monitoring carbon dioxide concentrations in the air is crucial for maintaining a healthy environment.
【⚠️ Important Note】This device detects carbon dioxide (CO₂), not carbon monoxide (CO). It is an air quality monitor and cannot replace a smoke alarm or carbon monoxide detector.
