Introducing our Advanced 8-in-1 Air Quality Meter, a cutting-edge device designed to provide precise and comprehensive monitoring of your indoor environment. With its sophisticated features and user-friendly design, this air quality meter is an essential tool for maintaining a healthy living space. - **ACCURATE SENSING**: Equipped with a standalone CO2 NDIR sensor, our air quality meter offers superior accuracy and greater resistance to interference compared to traditional semiconductor sensors. This ensures precise measurement of carbon dioxide levels in the air, providing reliable data for informed decision-making. - **WITH ALARM**: The device includes a PM2.5 indoor air quality meter that uses color-coded warnings to indicate air quality levels: green (0‑50), yellow (51‑100), orange (101‑150), and red (greater than 151). An audible alarm is triggered when PM2.5 levels exceed 100, prioritizing CO2 alerts if both CO2 and PM2.5 are above the standard. This ensures you are immediately notified about any harmful air pollution. - **LONG ENDURANCE**: Powered by a built-in 2000mAh rechargeable lithium battery, the air quality meter can be fully charged in 3‑4 hours using the included USB charging cable with a DC 5V input. Once fully charged, it offers 7‑8 hours of continuous operation, providing long-lasting performance without frequent recharging. - **COMPACT AND PORTABLE**: Designed for convenience, the compact and portable form of the CO2 detector allows you to easily place it anywhere. This ensures you can consistently monitor CO2 levels, whether at home or on the go, offering flexibility and peace of mind. - **DETECTION OBJECT**: Our 8-in-1 air quality meter is equipped with five professional detection sensors, capable of accurately measuring indoor levels of CO2, PM2.5, HCHO, PM1.0, TVOC, PM10, as well as temperature and humidity. This comprehensive detection capability provides a holistic view of your air quality, ensuring a healthier environment.
