Overview of Our Conductivity Probes

Conductivity probes are designed for sorting nonferrous metals and determining heat treatment condition or damage.

Our conductivity probes with Powerlink technology are designed to be used with the following NORTEC 600 series models: 600C, 600S, or 600D.* These NORTEC 600 series instruments measure conductivity and display the results on the screen in either %IACS or MS/m, while simultaneously measuring the coating or lift-off factor in inches or millimeters.

Conductivity probes are available in frequencies of 60 kHz or 480 kHz and are supplied with a 16-Pin LEMO connector enabling Powerlink functionalities.

How do our conductivity probes and standards work?

Our conductivity probes use a system for measuring and certifying electrical conductivity of metals that operates using the four-point DC resistance technique for primary standards. These standards are maintained by Evident at all times and are recertified at set intervals to comply with NIST traceability. The primary standards and test pieces are maintained in a 20 °C (±10 °C) environment and the test pieces are measured using the AC impedance transfer method. The entire system is computer controlled for accuracy and repeatability.

Using this technique of primary standards, our conductivity probes are capable of certifying conductivity standards to a high degree of accuracy:

• Materials that are below 60 %IACS can be certified to 0.35 %IACS or better.
• Materials that are above 60 %IACS can be certified to 0.5 %IACS or better.

*Not compatible with the base NORTEC 600 model.
