Representing FISCHER in HungaryExclusive distribution of FISCHERMeasurement Technology in NIVELCONIVELCO established a partner relationship withSindelfingen based Helmut Fischer GmbH in 1985. ThisGerman company has developed innovative measuringtechnology for coating thickness measurement, materialanalysis, micro hardness measurement and material testingfor almost 60 years.The closer the magnet is to the steel surface, the strongeris the induced magnetic field. The thickness of the coatingdetermines how close the pole of the magnet canapproach the substrate, therefore layer thickness determinesthe strength of the magnetic field around themagnet placed on the test sample.The Fischer Company was founded by Helmut Fischer,a physicist, in 1953. At that time the rapidly developingautomotive industry needed thickness measurement ofcoatings and pore-exemption inspection. These measurementsare essential in monitoring the quality ofthe layers and the applied coating technologies (paintand galvanic coatings). The old testing method for thesemeasurements was to make a cut. The layer thicknesscan be examined on the cut by a microscope.The first non-destructive thickness measurement methodused the magnetic principle. The main point of thismethod is: the strength of the electromagnetic fieldaround the magnet is dependant on the pole of themagnet and the distance of the tested steel surface.8
