Measuring conductivity and/or resistivity

Hello colleagues,
Can anyone recommend a method and necessary equipment to accurately measure the electrical conductivity of metals? We need to determine and report the actual conductivity in IACS % of raw materials that we'll use to manufacture eddy current calibration standards. The product forms will be sheet, plate, bar, tube and pipe. Any advice will be greatly appreciated.

Re: Measuring conductivity and/or resistivity
there is an equipment (sigmatest) made by Foerster that is exactly for electrical condutivity measurment on non ferrogmagnetic metals
you can find that equipmente at:

hope that will help you

Re: Measuring conductivity and/or resistivity
Few years we use equipment made by GE Inspection Technologies - Phasec 2D. It is portable Eddy Current instrument with electrical condutivity measurment option.
You can see that equipmente at:

Re: Measuring conductivity and/or resistivity
Also we make an instruemnt for only measuring conductivity called to AutoSigma 3000. More information available here;http://www.geinspectiontechnologies.com/en/products/eddy_current/autosigma.html

In addition to the testing device, I would advise you to purchase a set of NIST traceable standards in the conductivity range you are working in.

Lyft™: Pulsed Eddy Current Reinvented

PEC Reinvented—CUI Programs Redefined Corrosion under insulation (CUI) is possibly the greatest u
...
nresolved asset integrity problem in the industry. Current methods for measuring wall thickness with liftoff, without removing insulation, all have severe limitations. Eddyfi introduces Lyft — a reinvented, high-performance pulsed eddy current (PEC) solution. The patent- pending system features a state-of-the-art portable instrument, real- time C-scan imaging, fast data acquisition with grid-mapping and dynamic scanning modes, and flexibility with long cables. It can also scan through thick metal and insulation, as well as aluminum, stainless steel, and galvanized steel weather jackets. Who else but Eddyfi to reinvent an eddy current technique and redefine CUI programs. Got Lyft?
