Hull cells are commonly used in the analysis of a variety of plating baths. One limitation of the Hull cell analysis is the difficulty in maintaining uniform agitation of its cathode surface. Because uneven agitation can lead to an ambiguous boundary resulting in the wrong interpretation of the quality of plating, an agitation system that overcomes this limitation is described below. A funnel-shaped cone 1 (Fig. 1) is inserted into a hole 2 of a cylindrical container 3. The end of the cone 1 is a cylindrical tip 4. The cone 1 and container 3 are made of an appropriate insulating material. A strip of cathode 5 is attached to the side of cone 1, and an anode 6 is placed on the wall of container 3. The cone 1 is rotated by a shaft 7 that is connected to cone 1.
