Mi-Glow® 834

Water-Based Fluorescent Powder for Magnetic Particle Inspection

Our Solution Results in:

  • Reduction of Mi Glow 834 consumption in NDT processes
  • Greater sensitivity and brightness of the Mi Glow 800 results in faster NDT inspections
  • The use of the efficient Wetting Agent 34 provides a cost savings by reducing magnetic particle consumption

Mi-Glow® 834 uses our latest generation
Mi-Glow 800 particles.

Mi-Glow® 834 uses or 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. Borate free Wetting Agent #34 helps to alleviate potential health and safety concerns associated with chemistries containing borates. 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. Mi-Glow® 834 is designed to be used with UV-A light to detect discontinuities typically found in the NDT of forgings, castings, welds, and high-volume NDT applications.

It is designed to be used with a UV-A light to detect discontinuities typically found in the NDT of forgings, castings, and welds.

Mi Glow


  • 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 (MG 834 requires 5 g/L compared to our direct competitor of 11.25 g/L)

Provides total particle encapsulation, eliminating free unbonded pigment, resulting in a low background, high performing magnetic particle inspection powder

Sensitivity – The superior Mi Glow 800 particles have larger surface areas which mean smaller sized particles with increased sensitivity and brightness
