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.
