The electroplating technology is known to include all processes for surface treatment of metals and non-metals for using in the manufacture of metallic coatings from electrolyte solutions and molten salts by transport of ions and electrons. Electroplated produced Metal layers and coatings have, in dependence of their intended use, certain characteristics, being able to meet different demands of aesthetic or technical nature. Using the surface technology the quality and usability of products are affected significantly. Today it is hard to imagine that an industrial sector could do without need of electroplating coated parts.

A strongly inhomogeneous current density distribution can lead mainly to an impairment of the quality of the galvanized work pieces with unpredictable and costly consequences.

By means of the real-time measurement of the current density distribution selective countermeasures can be taken, such as use of conductive and nonconductive auxiliary cathodes or cover plates, in order to check the result of the measures in a relatively short time.

For the first time in 2007 a concept for a measurement system was proposed and developed by the founder of the later Engineering Office PhysiTronik (see picture above). By means of this equipment the current density distribution could be determined under limited conditions in a laboratory scale.

Between 01.09.2009 to 31.08.2011, in the framework of the SME innovative collaborative project "Real-time Measurement of the Current Density to Increase Resource Efficiency in Electroplating Production" - in German: "Echtzeitmessung der Stromdichte zur Steigerung der Ressourceneffizienz in galvanotechnischen Produktionen" (in short: EmSiG) - intensive and systematic research and development activities were performed to develop a measurement system for the real-time measurement of the current density in electroplating baths. Finally in this joint project for the first time, in a cooperation of the Fraunhofer Institute for Manufacturing Engineering and Automation (IPA), DIGALOG GmbH and Engineering Office PhysiTronik a measurement system was developed which made measurement of the current density in the electroplating bath possible. So the test device Galvanoscanner GS01 was developed. The product GalvanoScanner GS02 is now CE-certified and serially manufactured availabe!
