The coulometric or anodic de-plating technique is used for measuring the thickness of electroplated coatings on virtually all substrates such as steel, non-ferrous metals or insulating material bases. Typical applications include: nickel on steel, zinc on steel, tin on copper, silver on copper or copper on epoxy This technique simply involves the removal of a small, almost invisible area of coating material. The substrate is not affected. The coulometric method ensures reliable and exact results. Designed for complete ease of use, GalvanoTest requires no specific operator skills and only minimal training before actual measurements can take place. The coulometric principle is the only low-cost method to measure the individual layers of multi-layer systems, for instance chrome plus nickel plus copper on steel one after the other. Connected to the MiniPrint data printer, GalvanoTest provides complete documentation of measuring results and statistics. For specific measuring analysis or later reference, the characteristic voltage curve during the de-plating process can also be printed out.
