A two-channel analyzer of optically dense flammable aerosol fluxes based on two parallel diode optocouplers with a wavelength of electromagnetic radiation λ=0.65 and 3.4 μm, a speed of tau≤ 0.05 s and the transmission of digitized data to a server up to 1200 m away via the RS-485 interface has been developed. Its design and characteristics in the process of detecting particle streams with a diameter of 0.2 to 5000 μm with an optical density of D≤3.5 are described. It is shown that the values of the ratio of wave attenuation coefficients with λ=0.65 and 3.4 μm to the droplet size calculated on the basis of the theory of radiation scattering Mi are consistent with the experimental ones. The created aerosol analyzer can be used in the express analysis of technogenic airborne emissions of fuel liquids and for the development of large-scale generators of explosive type when creating pulse barriers from clouds of finely dispersed aerosol in the atmosphere. Keywords: aerosol analyzer, speed, diode optocouplers, infrared and visible radiation, attenuation factor, optically dense emissions, Mi scattering theory, fuel liquids.
