Model XYD-3 rotating ring-disk electrode has been designed and producted to make accurate measurement in electrochemical research. This paper gives a brief description of the theory and application of the ring-disk electrode and detailed with the principle of its mechanical structure and electrical device. The results measured by the instrument have shown that the wobble at the end of the electrode is less than 0.015mm. The collection efficiency N measured by the electrochemical experiments was essentially in agreement with its theoritical designed value. i-w(1/2) relationship showed good linearity. The technical verification has demonstrated that model XYD-3 rotating ring-disk electrode is an ideal instrument which can be applied in electrochemical research.
