The SIGMASCOPE® SMP350 measures the electricalconductivity using the phase-sensitive eddy currentmethod, which is approved by both DIN EN 2004-1and ASTM E 1004 for determining conductivity. Thiskind of signal evaluation allows for contact-free determinationof a substrate’s electrical conductivity, evenunder paint or plastic coatings up to 500 μm thick.This method also marginalises the influence of surfaceroughness.

• Measurement frequencies ranging from 15 kHz to 2 MHz, depending on the probe• Measurement range: 0.5 – 65 MS/m or 1 – 112% IACS
ApplicationsThe SMP350 can measure the electrical conductivityof any non-magnetisable metal. Furthermore, since theelectrical conductivity provides data about other materialproperties, it is effective in a wide range of measuringapplications and fields of use, including:• Quality assurance and sorting of raw materials• Authentication of coin alloys (e.g. specificconductivity of Euro coins)• Assessing hardness and strength of heat-treatedmaterials• Inspecting for heat damage, material fatigueand cracks• Estimating the phosphorous content in copper• Tracking precipitation processes, e.g. forCu-Cr alloys• Testing the homogeneity of alloys• Scrap metal sorting

X-ray fluorescence instruments are an advanced range of analyzing instrument which found applications in various industries. These X-ray fluorescence instruments are widely used for analysis of metals, non destructive coating thickness, metal analysisn and RoHS screening . These work on the principle of X-ray emission and excitement of atoms.
