ABSTRACT:
An electrode probe for accurate corrosion current measurement of metals in ionically conducting liquids. Electrode, and insulator to probe holder, are cylindrical surfaces of the same diameter, to combine minimum disturbance of liquid flow past electrode surfaces with substantially uniform density of current passed between the electrodes. Elastic outside shields form water-repellent interfaces that substantially exclude crevice corrosion and define exposed electrode length and area with precision.
