A range of comparators for inspection on shot, grit & sand blasted surfaces.
Surface comparators are used to compare freshly blasted profiles to pre-defined profiles. The comparators are available as grit, shot or sand and comparisons can be made visually or by touch. This method is ideal for providing a very quick guide to the profile.
