If you are only required to quickly assess the surface profile of a blasted metal surface, then the easily transportable and easy to use Surface Comparators are the perfect choice. Put simply, comparators are a flat, steel plate which contain a number of reference surface profiles, formed on a corrosion resistant metal.
