This paper describes new, unparalleled developments by Soyuztsvetmetavtomatika JSC, and namely new devices designed to determine the concentration of sulphuric acid and sodium hydroxide aerosols in the air of industrial sites. A situation is described related to the need to develop a reference generator for conducting tests. The paper contains descriptions of the developed GRANTA generator and GRANT-KShch detector, which were included in the State Register. The authors point out the importance of keeping under control potential situations related to sulphuric acid spills. For this, a sulphuric acid spill detector SAKS-1 has been developed. This device measures the magnitude of the current flowing through the sensitive element, or the electrode potential. The SAKS-1 device comprises a control unit and transducers with electrochemical sensors placed in special adapters. The number of transducers corresponds to the number of potential leakage points and can range from 1 to 8. The device is included in the State Register of the Russian Federation and is supplied to many production sites.
