AUTOMATIC DUST METER PARTICLE-SIZE ANALYZER

This paper presents the results of the development of a new photoelect ric aerosol counter designed for measuring the differential count conc entration of dust particles of sixteen size gradations and for determi ning the total count and total mass concentration. Its main technical and operational characteristics are compared with those of similar dev ices, its advantages are enumerated, and its operating principles and structural layout are described. Experimental results and error estima tes are presented. Some possibilities for measuring aerosols are illus trated. (C) 1996 The Optical Society of America.
