Also known as Grit Comparator, Shot Comparator Blast-cleaned Steel Comparator and Blast Comparator

Features

• When steel has been blast-cleaned, the surface consists of random irregularities with peaks and valleys that are not easily characterised.
• Because of this random nature, it is recommended that the profile should be identified as either angular (where grit abrasives have been used) or dimpled (where shot abrasives have been used) and that they should be graded as fine, medium or coarse using the four segments on the Comparator.
• Fine-grade profiles equal to segment 1 and up to but excluding segment 2.
• Medium-grade profiles equal to segment 2 and up to but excluding segment 3.
• Coarse-grade profiles equal to segment 3 and up to but excluding segment 4.
