DMA
Differential Mobility Analyzer

The Differential Mobility Analyzer (DMA) is an in situ device that measures particle electrical mobility to determine their size distribution. It primarily measures aerosols between 10 and 1,000 nm in diameter. The DMA can be used for airborne, ground-based, and laboratory measurements.
