The APDA-372 dust monitor is specifically designed for indoor and outdoor air quality measurements and provide continuous and simultaneous measurements of PM1, PM2.5, respirable fractions (PM4), thoracic fractions (PM10), inhalable fractions (TSP), the particle number, and (upon request) the particle size distribution in 32 size classes per decade within the particle size range of 0.18 – 18 µm. The APDA-372 uses the recognized measurement technology of optical light scattering and is equipped with a white LED light source with highly stable output and long lifetime. The system is also equipped with a filter holder for the insertion of an absolute filter (47 or 50 mm in diameter). This enables the user to perform on-site gravimetric correlation or subsequent analysis of the composition of the aerosol. The APDA-372 can be connected to an isokinetic sampling probe that measures emissions in exhaust air ducts. The volume flow is 5 L/min. The APDA-372 is additionally equipped with sensors for measuring environmental conditions, such as temperature, atmospheric pressure, and relative humidity.
