Electrical Conductivity Meters

Electrical conductivity (MS/m or % IACS) is a quick indirect indicator of the properties of non-ferrous metals: it is used to assess heat treatment condition, the hardness and strength of aluminium alloys and alloy homogeneity, and to detect thermal damage and fatigue. Helmut Fischer SIGMASCOPE instruments use the phase-sensitive eddy current method according to DIN 50994 and can measure through paint or plastic coatings. SIGMASCOPE GOLD versions are designed to check the authenticity of gold bars and coins – they detect tungsten inclusions that a density test does not reveal.

Helmut Fischer SIGMASCOPE SMP350 – electrical conductivity meter for non-ferrous metals

Compact handheld instrument for measuring the electrical conductivity of non-ferrous metals – aluminium, copper – using the phase-sensitive eddy current method.

Helmut Fischer SIGMASCOPE GOLD B / GOLD C – gold authenticity testing by conductivity

Handheld instruments for the gold and precious metals industry – non-destructive authenticity testing of bars, coins and large jewellery within a few seconds, even through plastic packaging.
