Penetrant System Monitor Panel,A stainless steel panel, 0.090" thick and measuring 4 x 6 inches. A chrome plated strip runs the length of one side of the panel. Five crack centers are evenly spaced in the chrome plating in order of magnitude; the largest is readily visible with low sensitivity penetrants, while the smallest is difficult to observe even with high sensitivity materials. Adjacent to the chrome plated section is a grit blasted area of "medium roughness", to judge penetrant wash characteristics.
