The microAethalometer^™ MA600 is a real-time, 5-wavelength UV–VIS–IR rack-mount monitor for equivalent Black Carbon (eBC). It features an 85-position automatic filter tape advance system, enabling long-term, continuous operation with DualSpot^® loading compensation, necessary for accurate source apportionment measurements.

The MA600 incorporates a long-life brushless diaphragm pump, closed-loop flow control, onboard data storage, an altimeter/barometer, and sensors for relative humidity and temperature. An optional built-in aerosol dryer is available for improved measurement stability in varying humidity conditions.

Designed as a regulatory reference-grade network monitor, the microAethalometer^™ MA600 can be installed at fixed monitoring sites, in mobile monitoring vehicles, or in laboratories for extended continuous measurement campaigns requiring minimal maintenance and infrequent site visits. The 85-position filter tape cartridge supports continuous sampling of high concentrations for up to a year, depending on environmental conditions and instrument settings.

The multi-wavelength spectrum measurement delivers insights into the composition of light-absorbing carbonaceous particles, enabling differentiation of optical signatures from combustion sources such as diesel, woodsmoke, biomass, and tobacco. The proven DualSpot^® method corrects for optical loading effects while providing additional data on aerosol optical properties.
