Eddy Current Conductivity Meters for Metals
A conductivity meter for metals measures the electrical conductivity of non-ferrous metals such as aluminium, to sort alloys and check heat treatment without damaging the part. Asia NDE supplies the SigmaCheck 2 eddy current conductivity meter from ETher NDE across Malaysia and Southeast Asia. We serve aerospace, automotive and fabrication customers, with calibration and repair support from our Subang Jaya office. It is not a water conductivity meter.

What it’s used for
- Sorting aluminium and other non-ferrous alloys that look the same.
- Checking that heat treatment has been done correctly.
- Investigating heat, fire and lightning damage on aircraft structures.
- Measuring non-conductive coating thickness, such as paint, up to 0.5mm.
- Reading conductivity in % IACS or MS/m, from 0.5 to 110% IACS on the SigmaCheck 2.

Frequently asked questions
Is an eddy current conductivity meter the same as a water conductivity meter?
No. An eddy current conductivity meter measures the electrical conductivity of metals, such as aluminium, to sort alloys or check heat treatment. Water conductivity meters measure dissolved salts in liquids and are a different instrument.
What units does a conductivity meter for metals use?
Conductivity of metals is usually given in % IACS (a percentage of the International Annealed Copper Standard) or in MS/m (megasiemens per metre). The SigmaCheck 2 reads from 0.5 to 110% IACS (0.28 to 64 MS/m), which covers aluminium, copper and most other non-ferrous alloys.
Do you calibrate and repair conductivity meters?
Yes. Asia NDE runs a manufacturer-approved calibration centre, with repair support in Malaysia, for the conductivity meters and conductivity standards we supply.
