TECHNIQUES AND EVALUATION OF AEROSOL MEASUREMENTS
Abstract
The casc de impactor is used in connection wit he calibration of e Technol total lightsca tering meter. In the compact Technol meter, the mou t of sc r d light due to a small illumina ed sample of par icl -carryi g osphere is related directly to the range of visibility as seen by the human eye I N V LUATI G THE NUMBER OF PARTICLES ON THE Casella Casca e Impactor the halo effect an sampling efficiency must be considered; otherwise, counting-error of up o 00% will re ult It is pos ible to calibrate a lig t-scatt r uri g instrument, such as the T ECHNOL MET R, BY USING A HO OGENEOUS LATEX AEROSOL. Th fi ld tests of the Tec nol meter compared favorably wi h the laboratory c libratio tests. T HE INSTRUM NT MUST BE MODIFIED TO COMPENSATE FOR HUMIDITY ND LO IG L- O- OI R IO. (Author)
