FIELD: measuring technique.
SUBSTANCE: device comprises reference electrode (2), auxiliary electrode (3), polarization switch (4), and measuring unit (5) for measuring input potentials at inputs (51) and (52) with respect to common bus (6). The electrodes (2) and (3) are connected with the measuring inputs of unit (5). The common bus of unit (5) is connected with the object. The unit calculates the potentials of electrochemical corrosion protection from the data of measurements of the input potentials.
EFFECT: enhanced precision and reliability.
