Abstract
Apparatus for measuring electrical potential in a cell, especially at a point close to a sample electrode, comprises an accommodation for a reference electrode, a modified luggin tube, elements for locating the sample electrode, and supports for both the luggin tube and the locating elements, respectively, the supports being fixed relative to each other. The apparatus requires less skill in the positioning of the sample electrode close to the point at which electrical potential is measured and is less vulnerable to inadvertent disturbance.
