MTU-3 MPI Reference Block

Cracked Test Piece for the Evaluation of Magnetic Particles

The MTU-3 Test Block is used to check the sensitivity of magnetic particle materials, assess material degradation and assess bath contamination. This two-sided block has a variety of indications ranging in size from small to large and each block has a completely unique crack pattern that mimics natural cracking. Can be used with fluorescent or visible particles. For application, ensure the block is free from dust, oil and other repellent materials before applying a well-mixed inspection medium. Compare your results with the supplied reference photograph before cleaning your block immediately to avoid permanent indications.
