Aethalometer : Portable Model AE42
Portable Aethalometer® Model AE42
The AE42 Portable Aethalometer measures optical 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 “full size” AE22, but it is constructed in a small portable case with an internal battery providing several hours of mobile operation. The AE42 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 “seven wavelength Spectrum” optics upon request. The AE42’s can be supplied with a GPS position receiver kit that attaches to the instrument's COM port. The instrument can then record the GPS position input data for mapping in mobile or survey use.
