Representing FISCHER in HungaryThese instruments, using the magnetic inductionprinciple, are available in small handheld typesand there are also desktop versions. Today’smodern instruments provide a data-loggingcapability to even make statistical calculationson the measured values in a single handheldinstrument.Similarly to the above measurement method,the Eddy current method provides measurementof non conductive (varnish, plastic, oxide)coatings on ferric materials. There are compactinstruments operating with both (magneticinduction, and eddy current) methods usinginterchangeable probes. The instruments consistof a measurement probe and a signalprocessing/displayunit.The probe can be incorporated in theenclosure, or can be connected with a cable tothe enclosure. There are numerous probe typesand instrument versions in order to provide theproper solution for any measurement task.Unfortunately the above measuring methods are not suitablefor the measurement of multilayer coatings, magneticcoatings on steel, metal coatings on plastics, not tomention the material analysis of the coatings.The X-ray method was developed to satisfy this purpose.The main point of this method is to radiate X-rays into thetest sample.The energy of the reflected X-ray depends on the quality ofthe irradiated material, while the intensity of the reflectedX-ray depends on the thickness of the irradiated material.Therefore many types X-ray spectrometers were developedto create suitable instruments for high-precision thicknessmeasurement and material analysis. The X-ray method allowsexamination of very small structures (PCBs, connectors),or the trace analysis required by the RoHS directive.NIVELCO Process Control Co. - as the exclusive Hungariandistributor of the Fischer Company - has been importingand selling fair amount of Fischer instruments and widerange of probes on the domestic market over the years. Moreoverthe sales we provide include repair and maintenanceservices, assistance to our customers in choosing the appropriateinstrument type, as well teaching the proper useand handling of the instruments to the end-users.Dr. Ferenc HaskóFISCHER Product ManagerNIVELCO Co.fhasko@nivelco.com9
