Luke-NDT MT-6 Rechargeable Rotating Field Yoke

Luke-NDT MT-6 Rechargeable Rotating Field Yoke

Field Magnetic Particle Yoke, Ideal for Seam Welds and Large Surfaces

★ Coming Soon ★


Magnetic Particle Inspection (MPI) of seam welds and large surfaces with a hand-held yoke is both labor intensive and time consuming. Since the material needs to be magnetized in two directions with overlapping shots, it is possible for the inspector to miss an area. The Luke-NDT MT-6 Rechargeable Rotating Field Magnetic Particle Yoke, however, offers an easier solution. This portable yoke can inspect in both directions at the same time with non-magnetic rollers for non-contact inspection. Features an IP 65 dust tight and water resistant design and can be used with any magnetic particle material. 



Inspect in Both Directions at the Same Time

  • The Luke-NDT MT-6 Rotating Field Yoke, magnetizes the material in both directions assuring that longitudinal and transverse flaws are detected. The field direction is alternated at line frequency (50/60 Hz)

Non-Contact Inspection

  • The test is non-contact, non-magnetic rollers create a 0.020” (0.5 mm) gap between the prods and the materials surface, allowing the MT-6 to be rolled across the length of the weld as the inspector applies the magnetic particles.

Use with Any Magnetic Particle Material

  • The MT-6 can be used with wet or dry, visible or fluorescent methods.


  • The MT-6 is truly portable and easy-to-use. Battery operation permits the use away from AC power supply, so the inspector is not tethered by a power cord


  • IP 65 dust tight and water resistant design and exceeds ASTM and ASME requirements


MT-6 Belt

A specially designed belt carries the battery and MPI consumables adding to the convenience and efficiency of the MT-6.
