Abstract. It is hard to imagine the development of the country’s economy without constant development and improvement of its base of standards in order to ensure the uniformity of measurements both in a particular country and at the global level. For this purpose, there are four state metrological institutes with branches in Russia.
The Research Department on Physicochemical and Electrical Measurements is a structural subdivision of The Federal State Unitary Enterprise “Russian Metrological Institute of Technical Physics and Radio Engineering”. The activity of the Research Department is related to the measurement of pH, pX, inorganic components in liquids, with measurements of the parameters of particles in various matrices, gases dissolved in a liquid, such as oxygen, hydrogen, carbon dioxide, measurements of the parameters of air ions, etc. Scientists of the Research Department conducting research to develop the certified reference materials in order to establish the measurement traceability to the Russian Primary Standards, to the calibration and measurement capabilities of metrology institutes at the database of key comparisons of the International Bureau of Weights and Measures.
The Research Department is constantly working to expand its capabilities for metrological support of industry and scientific research in the Russian Federation on the topics assigned to the institute, is actively working to improve its reference base, participates in technical committees and working groups of regional and international organizations related to metrology. Takes an active part in international and Russian conferences and seminars, round tables and discussions.
This paper describes the achievements of the Research Department over the past two years.

Keywords: primary standard, multielement reference material, CMC, measuring range, zeta potential, particle mass concentration, key comparison, pH.
