Magnetic Particle (MT)

The Magnetic Particle method can be used only on ferromagnetic materials to reveal surface discontinuities and to a limited degree, those located below the surface. The sensitivity of this method decreases rapidly with depths below the surface being examined and therefore, it is used primarily to examine for surface discontinuities. PTI offers large, stationary in-house test units for high volume inspection and a full range of portable units designed for reliable, efficient testing in the field.
