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, experts have 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 with each grade being defined by limits specified in ISO 8503.

The Surface Roughness Comparator is supplied in a protective Wallet.

The Surface Roughness Comparator can also be supplied with a X5 Illuminated Magnifier in an industrial foam-filled Carrying Case.
