NDT Protea FM-31 Fluorescent Magnetic Powder is a ready-mixed suspension of fine-grained fluorescent magnetic powder developed for professional magnetic particle inspection (MT/MPI) . FM-31 is used in conjunction with UV light (365 nm) to detect cracks and defects in ferromagnetic materials with very high sensitivity.

The fluorescent formulation in NDT Protea FM-31 provides strong and clear indications under UV illumination in dark environments, making the product ideal for demanding NDT inspections in industrial, offshore and quality control.

FM-31 is designed with low background fluorescence and a low-viscosity, low-odor carrier fluid, providing better inspection conditions and more accurate results. The product is free of corrosive substances such as sulfur and halogens.
