Abstract
The paper a refractometric device (URL-1) for measuring the concentration dependence of the refractive index in aqueous solutions of tetrachloroethylene is considered. The presented study is relevant and promising, since the identification of optical parameters in these media is important for chemical industries. The article the appearance of a laboratory refractometric installation, as well as technical and operational characteristics of refractometers used in measurements are presented. The results of measurements of the concentration dependence of the refractive index of the studied substances were obtained experimentally, which were compared with reference values from the scientific literature. The data of experimental measurements and reference values are compared with the results obtained on the K-Patents OY PR-03-M refractometer. The error of the experiment did not exceed k ≤ 0.4%.
