|GRIT is split into sections equivalent to:||25, 40, 70, 100 mkm|
|SHOT is split into sections equivalent to:||25, 40, 70, 100 mkm|
A precision nickel comparator plate which conforms to International Standard ISO 8503 for grit and shot blast surface roughness comparison measurement.
Comparators allow the estimation of surface roughness by touch and sight. They are split into four sections, each with a different and defined roughness.
Comparators are available in both grit and shot blasted versions.
