Particle analysis of the dust in outdoor air is a vital step in meeting EPA regulation for air quality. The high volume particle sizing impactors from New Star are used in conjunction with U.S. EPA high volume air samplers to measure the size of the dust in outdoor air. Particle analysis requires precise instruments, and Federal and State regulatory agencies can rely on the quality particle analysis instruments from New Star. We carry only the highest quality machines and back them with nearly 60 years of industry experience.
