Abstract

Nephelometers and photoelectric counters are the most widely used instruments for measuring the characteristics of aerosol particles. Due to peculiarities of the design of the used nephelometer, as well as limited to visible range spectral interval, sensitivity of the method is restricted to submicrometer aerosol fraction. On the contrary, counters provide for the data on the particles with diameters of 1 μm and more. Thus, combination of these two instruments makes it possible to extend the range of obtaining the reliable data on the aerosol microstructure. In this paper, the results are discussed of simultaneous measurements of the size spectrum by means of nephelometer and photoelectric counter at artificial humidification of aerosol in the range of relative humidity from 20 to 90%.
