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.
If you are looking for an Eddy Current (EC) Conductivity Meter, please take a look at the SigmaCheck-2. The SigmaCheck-2 is our fully featured Conductivity Meter and a perfect option for Conductivity Measurement in any Aircraft manufacture and maintenance fields where conductivity measurements are used to verify proper alloy/temper or detect heat damaged components.
