contracor src grit surface roughness comparator EXP The Spasciani ACS 951 isThe SRC GRIT Surface Roughness Comparator is a precision measurement tool that conforms to international standards for grit and shot blast surface roughness comparison. This comparator plate is split into four sections, each with a different and defined level of roughness, making it easy to estimate surface roughness by both sight and touch. The grit version of the SRC GRIT is split into sections equivalent to 25, 60, 100, and 150 microns, making it
