A set of two panels, each measuring 3.875 x 1.875 inches (100 x 35mm), sheared from the same stock with matching crack patterns. Makes simultaneous comparison of two penetrant batches practical. Specify crack sizes of 10µm, 20µm, 30µm, 50µm.
NiCr Test Panels
The NiCr penetrant test panels are ideal penetrant sensitivity comparators. The panels are available with crack depth of 10, 20, 30, and 50 microns and come in matched pairs. Individual crack sizes or a complete kit of all four sizes are available.
Having matched pairs enables studies of the effects of process changes as compared to a standard process, or used material changes vs fresh material. The panels are ideal for monitoring fluorescent penetrant (ZYGLO) lines.
