Eddy Current Tester

Defect detection in non-magnetic and magnetic bar, wire, or tube where multiple test channels and both encircling and rotary probe technology is desirable.


The instrument is packaged in a heavy duty cabinet that includes a built-in monitor, air conditioning, and pull- out keyboard. There is no need to access the cabinet interior during setup and operation.

The MultiMac® is also available in other cabinet configurations that do not include the heavy duty cabinet and built-in monitor. These models include output connectors for an external monitor, and can be housed in an environmental cabinet with air conditioning where needed.

The versatile new MultiMac® lets you configure your eddy current test application the way you want – all with just one tester. MultiMac® test channels can be individually configured for use with encircling or sector test coils as well as rotating test probes – eliminating the need to have several instruments.
Yet MultiMac includes the best features of MAC’s individual encircling coil and rotary probe instruments. Features include up to 8 test channels in any combination, and a broad test frequency selection from 1KHz to 5MHz. All test channels can operate simultaneously at the same or at different frequencies

MultiMac® can operate on a wide variety of non-magnetic products, or use Direct Current saturation systems to inspect magnetic material. Test speeds can range from one foot per minute up to several thousand. Installation can be in-line or at a separate test station. End suppression circuitry, when combined with an optional sensor can be used for testing cut lengths to prevent false signals from leading and trailing ends.
