Mi-Glow® 920 is fluorescent yellow-green particles

Mi-Glow® 920 is fluorescent yellow-green particles designed to be used with CircleSol M™, a refined petroleum distillate or Circle System’s wetting agents for use in water. The Mi-Glow 920 particles are manufactured with optimal sensitivity, brightness, and magnetic characteristics for wet method magnetic particle inspection. Mi Glow 920 fluoresces a vivid shade of yellow-green when viewed under UV-A lighting. When used with CircleSol M or a Circle System’s wetting agent, Mi Glow 800 will provide an exceptional inspection by leaving minimal background and zero particle clumping on the inspection surface. Mi Glow 920 is designed to detect discontinuities such as laps, seams, shrinkage, tears, and inclusions.

It meets or exceeds AMS 3044 and all applicable industry specifications.

  • Circle Systems unique bonding method offers a very tightly bonded particle which
  • Provides total particle encapsulation, eliminating free unbonded pigment, resulting in a low background, high performing magnetic particle inspection powder

Sensitivity – The superior Mi Glow 920 particles have larger surface areas which mean smaller sized particles with increased sensitivity and brightness
