MR®111HB is an ECOLINE, ultra bright fluorescent green-yellow (under UV), dry green, highly sensitive ferromagnetic powder designed to be used with oil or water (along with conditioner) which is used for Magnetic Particle Testing (MPT). MR111HB particles are manufactured for an optimum sensitivity, excellent discontinuity definition, brightness with minimal to nil background and magnetic characteristics for wet method fluorescent MPT. It detects medium to fine surface and slightly sub surface discontinuities such as cracks, inclusions, seams, tears, laps, flakes and other welding defects.

Magnetic particle inspection (MPI) is a non-destructive testing (NDT) method used to detect surface and slightly subsurface cracks in ferromagnetic materials such as iron, steel, and nickel. The process involves magnetizing the part to be inspected and then applying appropriate magnetic particles in the form of a dry powder or suspension to the surface of the part. The magnetic particles are attracted to areas of flux leakage, which are areas where the magnetic field is distorted by the presence of a crack or other defect creating a visible indication that can be used to identify and evaluate the nature and extent of the defect.
The application of the magnetic powder creates a visible indication of the location and shape of the crack or other defect. The powder accumulates at the location of the defect, forming a visible indication or "magnetic particle indication." This indication is then examined by a trained inspector using ultraviolet light or other illumination to identify the precise location, size, and orientation of the defect.
