Gar G-6 | 32 - 1000 Microinches Surface Roughness Comparator Scale w/6 Finish Specimens

Six replicated grit-blasted surface finish specimens ranging from 32 to 1000 Microinches.

The Gar G-6 Microfinish Comparator Surface Roughness Scale is made by a dual electroforming process wherein nickel is electrodeposited to provide an exact reproduction in intricate detail. The surfaces used in this scale are reproductions of accurately grit-blasted surfaces measured in microinches (millionths of an inch 0.000001"). The numbers engraved alongside each surface are the average deviation from the mean surface expressed in microinches. The G-6 Microfinish Comparator Surface Roughness Scale provides industry with established flat surface roughness specimens for visual and tactual comparison. It is used in specifying and controlling surface roughness when a product having the appearance of typically grit-blasted surfaces is required. The G-6 Microfinish Comparator Surface Roughness Scale provides an economical tool which permits roughness to be specified on the same basis as linear measurements.
