ABSTRACT:
The device comprises an electrochemical cell with polarization electrodes, a sample holder, a reference electrode with a capillary probe, a potential meter and a power supply source. The sample holder is mounted so that when a test sample is placed thereinto, the working surface of the sample is positioned perpendicular to the surfaces of the polarization electrodes. The polarization electrodes and the capillary probe are movably mounted.
