SigmaCheck-2 EC Conductivity Meter Curvature Correction Chart

The SigmaCheck-2 is our Eddy Current (ECT) Conductivity Meter and like any Conductivity Meter there is a set routine for operation.

The SigmaCheck-2 Probe needs to be flat on a surface to correctly read the conductivity. Therefore, if you have the probe on a curved surface (like a piece of round bar) the value that is shown on the SigmaCheck-2 is not the correct value of conductivity.

The SigmaCheck-2 Curvature Correction Table enables you to convert the displayed value on the SigmaCheck-2 to the actual conductivity value of the bar.

Simply find the diameter of the bar across the table. Read downwards until the reading on the SigmaCheck-2 is seen. Finally look across to the far left column and that is the real value in IACS of the material.
