MPI Testing Machine

The Magnetic Particle Inspection method of Non-Destructive testing is a method for locating surface and sub-surface discontinuities in ferromagnetic material.

Magnetic Particle Testing is the most reliable method for detecting surface cracks in steel and iron components. We offer you a great selection of equipment and supplies. Whether you need a portable Yoke or Coil, Portable or Mobile tester or a conventional or 3-D multi-directional Wet Horizontal Bench Tester we can provide you with the best value in equipment and supplies.

 It depends for its operation on the face that when the material or part under test is magnetized, discontinuities that lie in a direction generally transverse to the direction of the magnetic field, will cause a leakage field, and therefore, the presence of the discontinuity, is detected by use of finely divided ferromagnetic particles applied over the surface, some of these particles being gathered and held by the leakage field, this magnetically held collection of particles forms an outline of the discontinuity and indicates its location, size, shape and extent.

Dry magnetic particle examinations and wet fluorescent magnetic particle examinations are performed on ferromagnetic materials to detect surface and slight subsurface discontinuities. Specialized wet fluorescent magnetic particle techniques are available for black light internal examinations.
