FIELD: the invention is designed for measuring electrical conductivity of water and other electrolytes and may be used at physics-chemical investigations of liquids and also at automatic control of technological processes.
SUBSTANCE: the arrangement has a comparison block, a bipolar stabilizer of voltage, a source of current, a condenser, a resistor, three repeaters of voltage, four-electrode conductance-measuring cell. Besides three model resistors, three switchboards, a converter of the period into a code and a computing-controlling device are introduced.
EFFECT: increases accuracy of measuring.
