Mandrika Belgorod State National Research University, 85 Pobedy St., Belgorod 308015 Russia Journal Article 2022 02 21 The paper shows the need to develop a system for monitoring the concentration of suspended particles in the atmosphere, ensuring industrial safety at enterprises, facilities and in rooms with high dust content. The main possible consumers of this system are presented. Different measuring techniques of suspended particles and their fractions in the air are described, their advantages and weaknesses are mentioned. The technical requirements for the installation are noted. Discrete measurements via gravimetric method are depicted. Methods used and technical appearance of the installation are pictured. The composition, structure and operational principle of the installation are described. Attention is paid to the calculation, mathematical modeling and development of the analyzer optical scheme. https://cjes.guilan.ac.ir/article_5412_109d313f1aeb697ddce40a3da0d21bb5.pdf
