Cost Effective & Efficient 

Mi-Glow 834 uses the latest generation Mi-Glow 800 particles which have exceptional sensitivity, uniform size, and ideal magnetic characteristics for fluorescent magnetic particle inspection. Mi-Glow 834 is a fluorescent yellow/green powder premixed with borate free Wetting Agent #34 for use in water media. Wetting Agent #34 contains excellent corrosion inhibitors and offers incomparable defoaming properties ensuring a reliable magnetic particle inspection.

Mi-Glow 834 has excelled as an oil and gas tubular inspection product (OCTG). The high fluorescence, low foaming, minimal background, and consistently sized particles makes Mi-Glow 834 ideal for inspecting pipes that may have become blemished from being in service.



  • Borate free wetting agent with excellent wetting characteristics
  • Low foaming - Well controlled water conditioning agents
  • Economic - requires 55% less product to achieve desired concentration within a fluorescent MPI system, with savings of 53% per gallon of diluted MPI bath when compared to competitors
  • Provides total particle encapsulation, eliminating free unbonded pigment, resulting in a low background, high performing magnetic particle inspection powder
  • Greater sensitivity and brightness of the superior Mi-Glow 800 particles results in faster NDT inspections
