Circular and square cathode plates (test pieces).

For plating experiments and plating solution observation, cathode plates are made of 0.1 dm2 per side for easy calculation of current density.
The leads can be covered with heat-shrinkable masking tubes.
Materials: brass, copper, iron, aluminum

Usage Example of Mini Test Piece

• The phenomenon of plating can be observed and the liquid at the site can be controlled.
• The round shape of the mini-test piece allows uniform distribution of current, and can be used to measure the diameter of the phenomena that occur to control conditions.
• It can also be used to determine the amount of plating deposited.
