Concept, Design and Electronics for Control and Measurements of an Ecological Nephelometer

Engineering support of the natural and anthropogenic solid dust particles concentration measurement in the surface layer of the atmosphere implies the development and creation of a certain number of complex, but easy to manufacture and operate devices. The task takes on particular importance when considering dust as a means of transportation for various viruses and infections. The technical solutions we are considering boil down to the implementation of precision photometric measurements of light scattering by dust particles in liquid samples, the concentration of dust in which we increase to reliably measurable by photometry. The carried out research made it possible to formulate problems and propose solutions for a monitoring network. Technical solutions are implemented in working models and tested in urban dustiness of Tbilisi. (Abstract)
