For more information relating to Conductivity testing and our SigmaCheck 2 please refer to the following articles...
Please find following a basic introduction to conductivity and Eddy Current (ECT) Conductivity Measuring within Non-destructive Testing (NDT).
The SigmaCheck 2 Eddy Current (ECT) Conductivity Meter performs optimally when using a set operation routine. 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 will not be the correct value of conductivity.
Is gold a good investment? Of course, generally the answer is “Yes”… but be cautious, otherwise you may need a SigmaCheck 2!
