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.
