Overview

The CX-1A rotating disk electrode device RDE RRDE is one of the important tools for electrochemical measurement. Its main structure is to place a concentric ring on the same plane as the disk, and isolate the disk from the ring electrode with insulating material. The disk electrode is usually made of the material being studied, and the ring electrode is usually made of platinum or gold. In order to achieve excellent electrode performance, the rotating ring disk electrode must have special requirements in terms of machining accuracy, transmission device, speed measurement system, geometric shape, concentricity, and insulation performance of the ring electrode and disk electrode.
