Fischer Instrumentation’s new Dualscope MP0 system is designed to measure the thickness of coatings quickly and non-destructively, utilizing the magnetic induction and eddy current methods, the company says.
The probe-setting, measuring and reading instrument features the Fischer probe technology in its integrated measurement gauge. The unit offers one-hand operation and a measurement range of zero to 2,000um.
Quick and accurate measurement on site provides both flat and curved measuring samples, according to Fischer.
The Dualscope MP0 measures electroplated coatings of zinc, chrome, copper, paint, lacquer or plastic coatings on steel and iron. It is also suitable for paint, lacquer or plastic coatings on stainless steel or non-ferrous metals such as aluminum or anodic coatings on aluminum.
The instrument automatically recognizes the base material such as aluminum or steel and selects the appropriate measurement method.
For physical reasons, each measuring device shows an influence on coating thickness values depending on surface curvature. Although the unit’s measurement error is low, a steel diameter of 10mm delivers an error of more than 20% for the coating value, the manufacturer says. Such a curvature error is fully compensated by the device calibration, according to the company
The Dualscope MP0 can be used in areas with limited access. Calibration is required only in the case of extreme changes to shape or substrate material.
The instrument can display characteristic statistical values (mean value, standard deviation, minimum and maximum) of a measurement series. Another feature is the measurement with the free-running display for continuous scanning of surfaces.
