Handheld 10-In-1 Air Quality Monitor With Data Export To PC Detector For CO2, PM2.5, PM10, HCHO, TVOC, AQI, Temperature & Humidity, DM509

1. This 10-in-1 air quality monitor precisely detects critical environmental parameters, including carbon dioxide (CO?), PM2.5, PM1.0, PM10, Air Quality Index (AQI), formaldehyde (HCHO), Total Volatile Organic Compounds (TVOC), temperature, and humidity. It features data storage and wired export functions to help users track air quality trends over time.
2. Comprehensive 10-parameter monitoring—The device synchronously tracks and displays real-time readings for CO?, particulate matter (PM1.0, PM2.5, PM10), AQI, formaldehyde, TVOC, temperature, and humidity on a clear LCD screen, offering a complete overview of indoor environments.
3. Data storage and PC export function—Built-in data logging automatically saves measurements at preset intervals. Historical data can be exported to a computer via the included Type-C cable for in-depth analysis and long-term trend tracking using software like Excel, moving beyond reliance on single instantaneous readings.
4. Advanced multi-sensor fusion technology—Combines professional-grade sensors: an NDIR (Non-Dispersive Infrared) sensor for CO? detection, a laser scattering sensor for particulate matter, and electrochemical/semiconductor sensors for formaldehyde and TVOC. These work with a high-performance processing chip to ensure reliable and accurate measurements.
5. Broad applicability and technical specifications—Supports wide measurement ranges using standardized units, suitable for homes, offices, schools, and other indoor environments.
