Equipped with an ARM based 32-bit processor, this air quality detector delivers high speed processing, smooth operation, and precise readings. It monitors key pollutants to show environmental health levels, including carbon dioxide (CO2), formaldehyde (HCHO), total volatile organic compounds (TVOC), and particles PM2.5. These readings help you assess danger levels and track air quality over time. Color screen and intelligent control provide stable, fast performance and easy-to-read results. You can quickly view exact figures and trends at a glance. The device uses built-in sensors to accurately detect CO2, HCHO, TVOC and PM2.5, giving you a clear picture of air quality and potential pollutants in the environment. Compact, user friendly and reliable, suitable for home, office, or classroom use. It supports practical daily monitoring of indoor air to support healthier spaces. Use scenarios: - After renovation or new furniture installation, check for formaldehyde release and adjust ventilation as needed. - Daily indoor air quality monitoring for families or individuals sensitive to pollutants. - In offices or classrooms to verify ventilation effectiveness and maintain a healthy working or learning environment.
