Part no. 605-219

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
