Zusammenfassung:	A method consists in measuring ac impedance spectrum using gold, platinum or carbon working ultramicroelectrodes (1). The direct current DC potential pul se which overlaps with alternating current AC signal of an amplitude in the ran ge from 0.005 to 0.015 V and frequency in the range from 10-2 to 106 Hz is applied at the electrode. The value of said DC potential pulse for a process of copper electroefining is in the range from - 0.4 to - 0.9 V in relation t o a platinum reference electrode (2). Resistance values characteristic of a given electrolyte (E) are obtained from said AC impedance spectrum and compared with standard characteristic obtained by standard additions method. A measuring system consist of electrodes (1, 2, 3) placed inside a meauring ce ll (4) filled with flowing industrial electrolyte. The electrodes (1, 2, 3) are joined to a spectrum analyser (12) controlled by a programming apparatus (13 ).
