- ARM based processing provides 32-bit high-speed performance, greatly increasing computing speed and making detection more accurate and smoother. - Dynamic hazard tracking for gases such as formaldehyde and TVOC enables systematic recording of environmental health over time. - The air quality tester is suitable for use in homes, offices, businesses, government facilities, and schools. - Built-in electrochemical sensors can accurately detect carbon dioxide (CO2), formaldehyde (HCHO), volatile organic compounds (TVOC) and fine dust (PM2.5/PM10); readings may include toluene and other harmful chemicals and pollutants in the air. - Use scenarios: 1) In a home, monitor air quality after renovations and track changes in formaldehyde and VOCs over time. 2) In an office, maintain safe CO2 levels and manage VOCs from desks, printers, and cleaning products. 3) In schools or government buildings, support environmental health programs with continuous air quality monitoring and data logging.
