A differential refractometer design is proposed, which allows to obtain measurement accuracy in liquid environments up to 10‑6. The is intended for monitoring the parameters of a liquid medium by measuring the refractive index of the analyte in relation to the solvent. The refractometer allows the refractive index of liquids to be measured and the concentration of substances to be determined. The refractometer can be used in pharmacology, perfumery, chemistry and the food industry.
