Ecological Systems and Devices Annotation << Back Concentration meters KN-2m end KN-3 – is the device of ecological control of petroleum products, fats and nonionic surfactants in natural objects Vasilenko Yu.G. Korikov A.M. Ornatskaya G.N. The monitoring of dangerous substance concentration is the main activity for prevention and decrease the level of environment pollution. The up-to-date device concentration meters KN-2m end KN-3 that allow one to fulfill the measurements of petroleum products, fats and non ionic surface-active agents mass concentration in waters is designed for these tasks solution. The specifications and peculiarities of the developed procedures for quantitative chemical analysis, state standard samples of substance composition and materials as the base of concentration meters KN-2m end KN-3 measurement assurance are shown. Keywords: Petroleum products; fats; nonionic surfactant in natural objects; Concentration meter KN-2m; Concentration meter KN-3; Procedures for quantitative chemical analysis; State standard samples of substance composition and materials.
