APDA-372
Ambient Dust Monitor
The APDA-372 is a sensitive ambient dust monitor engineered for both indoor and outdoor air quality assessment. It simultaneously measures multiple particulate fractions—PM1, PM2.5, PM4, PM10, TSP—alongside particle number concentration and, optionally, size distribution across 32 classes for particles sized 0.18–18 µm. The system utilizes stable LED-based optical light scattering and supports gravimetric validation via absolute filters, offering precise, real-time aerosol analysis.
