Features

• To achieve the best inspection effciency
• To form a strong manetic field with a AC or DC type
• To apply dry, wet and fluorescent magnetic particles
• Excellent durability by using a molding type of rubber material with strong water-proof, shock  resistance
• To test various objects to be tested by connecting middle poles

Principles of Magnetic Particle Testing

When the material or part under test is magnetized, discontinuities which lie in a direction generally transverse to the direction of the magnetic field will cause a leakage field to be formed at and above  the surface of the part. The presence of this leakage field and therfore the presence of the discontinuity is detected by the use of finely divided ferromagnetic particles applied over the surface , some of these particles being geared and held by the leakage field.
The magnetically held collection of particles forms an outline of the discontinuity and indicates its location, size, shape and extent.
