FIELD: hydrometallurgy, monitoring of processes of beneficiation, determination of parameters of ion composition of technological products in pipe-lines and tanks under pressure. SUBSTANCE: given device includes body, filtering and insulating partitions, measurement zone, electrochemical sensor, branch pipe to drain filtrate, fixture to adjust pressure in measurement zone, fastening fixture holding body in technological flow, shut-off fixture to isolate filtering partition from pulp and fixture controlling passage rate of filtrate through measurement zone coming in the form of pneumatic valve, for instance. Liquid is supplied into measurement zone and discharge from it through additional hole in insulating partition. hole. Such design of device ensures accurate, uninterrupted control and possibility of maintenance in technological flows under pressure, for example, in pipe-line or tanks. There appears convenience to avoid usage of vacuum and considerably prolong service life of filters thanks to prevention of avalanche filtration mode at initial interval of operation. EFFECT: increased accuracy and reliability of measurements. 2 cl, 2 dwg, 1 tbl
