The Hull Cell Test
The cathode panel (Hull cell panel) in a Hull cell test typically measures 100 mm in length and 75 mm in width. It's often made of brass or steel. The anode, which is a separate piece, is usually 75 mm x 50 mm x 7.5 mm. The Hull cell itself is a trapezoidal container, and the most common size holds 267 ml of solution.
