10-In-1 Air Quality Monitor With Data Export To PC Detector For CO2, PM2.5, PM10, HCHO, TVOC, Temperature & Humidity, DM72B

1. This 10-in-1 air quality monitor accurately 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 capabilities, enabling users to 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, providing a holistic overview of your indoor environment.
3. Data storage and PC export function—Built-in data logging automatically saves measurements at preset intervals. Using the included Type-C cable, historical data can be exported to a computer for in-depth analysis and long-term trend tracking in software like Excel, eliminating reliance on single instantaneous readings.
4. Advanced multi-sensor fusion technology—Utilizes 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; paired with a high-performance processing chip to ensure reliable and precise measurements.
5. Portable charging design—Features a built-in rechargeable lithium battery (Type-C charging support) and compact dimensions of 145x78x97mm. Lightweight and portable, it can be easily moved between rooms or locations.
6. Broad applicability and technical specifications—Supports wide measurement ranges (e.g., CO? 400–5000 ppm, PM2.5 0–999 μg/m3) using standard units. Suitable for homes, offices, schools, and other indoor environments.
