APDA-372
Air Pollution Dust Analyzer
The APDA-372 ambient air quality monitoring system provides continuous and simultaneous real-time measurements of PM1, PM2.5, PM4 (respirable fractions), PM10 (thoracic fractions), TSP (Total Suspended Particulates) and particle number concentration.
Based on the QAL1-approved (EN 16450) optical light-scattering principle, the system is equipped with an LED light source offering highly stable output and a long service life.
With an aerosol flow of 4.8 L/min, the analyzer is equipped with a Sigma-2 sampling head, allowing representative measurements even under strong wind conditions. Furthermore, the sampling system features an Intelligent Aerosol Drying System (IADS) as well as sensors for measuring ambient temperature, air pressure and relative humidity. The IADS prevents erroneous particle classification caused by moisture.
