Cadmium Reference Electrode
A laboratory reference electrode with a cadmium rod or wire immersed in an electrolyte, used to provide a stable potential for electrochemical measurements such as pH testing and corrosion analysis. It is classified as an article of cadmium under tariff item 8112.69.00 because it is a finished product of cadmium, not a raw or semi-finished form.
