Measuring the Electrical Conductivity of Nonferrous Metals
Electrical conductivity is an important material property that provides information not only about a metal’s ability to conduct electrical currents but also about its composition, micro structure and/or mechanical properties. Using the SIGMASCOPE® SMP350, it is easy and quick to determine the electrical conductivity with precision and accuracy.
Measurement principle
The SIGMASCOPE® SMP350 measures the electrical conductivity using the phase-sensitive eddy current method, which is approved by both DIN EN 2004-1 and ASTM E 1004 for determining conductivity. This kind of signal evaluation allows for contact-free determination
of a substrate’s electrical conductivity, even under paint or plastic coatings up to 500 μm thick. This method also marginalises the influence of surface roughness.
