Particle Size Analyzer AimSizer 2011 works with principle of Mie Scattering to precisely determine the particle size distribution from 0.1 to 500 micrometer. This equipment has a few advantages all its own.Robust laser diode and innovative photocells optimize the precision of static light scattering and give AS-2011 a longer operational lifetime. Patented optical bench uproots light path deviation, one of the major technical problems in the industry of particle size analysis. User-friendly program and advanced algorism bring accuracy and repeatability qualification to International Norm ISO13320-1 Particle Size Analysis-Laser Diffraction Method. AS-2011 has become the most reliable and cost-effective LPSA and being widely used in micron particle size characterization.
