Contracor SRC-GRIT Surface Roughness Comparator

The 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 an essential tool for any professional who needs to measure and compare surface roughness levels.
