Rotating disk electrode oxygen sensor and corrosion rate probe

A rotating disk electrode (RDE) is applied as a dissolved oxygen sensor and corrosion rate probe. As an oxygen sensor, the RDE is capable of \pm0.004 -ml/l resolution and \pm0.17 -ml/l accuracy. As a corrosion rate probe, the RDE behaves more closely to theory than stationary electrodes. These applications make use of the RDE's unique hydrodynamic properties.
