Describing of the system of automatic selection, delivery and preparation of samples from solution, including distant sample delivery from the place of their primary selection to measuring devices for analytic control at hydrometallurgical enterprises has been given. This system has passed successful industrial tests at The Nickel Plant of Polar Division of Mining and Metallurgical Company Norilsk Nickel. The schemes of sample providing for analytic control of products of copper and iron-cobalt cleaning of electrolytes of nickel production has been presented. Found technical solutions depends on necessities of customer and allow to establish different configuration of the system of automatic selection, delivery and preparation of samples of solution in metallurgy, chemistry and another industrial branches, including food industry.
