Abstract
Precision equipment is described for reproducing the unit of numerical concentration and size for particles in aerosols, suspensions, and po wders in the concentration range from 4.10(7) to 4.10(13) m(-3) with a verage particle dimensions of 1-100 mu m. The apparatus is based on sm all-angle loser-beam scattering and Beer's law. The optical system is described. The residual systematic error in reproducing the numerical concentration and unit does not exceed 12% in the above concentration and size ranges.
