The Portable Aethalometer® Model AE42 measures light absorption by suspended aerosol particles at two wavelengths: 880 nm (IR), quantitative for the mass of ‘Black’ Carbon; and 370 nm (UV), indicating aromatic organic compounds. The instrument’s analytical performance is identical to the Rack Mount Aethalometer® Model AE22, but it is constructed in a small portable case with an internal battery providing several hours of mobile operation. The Portable Aethalometer can also be operated from an AC transformer or by cables from an external battery or automobile power outlet. This instrument is widely used for studying indoor air quality, and for the mobile mapping of the air quality impacts of localized sources.
The Portable Aethalometer may also be supplied with 7 wavelength light sources upon request.
