About this item

  • Our part # GAR-C9
  • Place the microfinish comparator surface roughness scale alongside your work piece
  • Slide the scale so that the rectangle with the surface roughness you want is adjacent to the piece you are examining
  • Compare by drawing the tip of the fingernail across each surface at right angles to the tool mark
  • The feel of the fingernail contact must be the same if the finishes are identical
  • There are nine replicated cast surface finish specimens ranging from 20 to 900 microinches
  • The C-9 cast microfinish comparator is rectangular in shape (4 1/2"x 3 1/4") and is a corrosion resistant electroformed nickel duplicate of actual cast surfaces
  • Supplied in a leatherette case with engineering data and instructions


The C-9 Cast 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 same electroforming process used to produce the Surface Roughness Scale is available from GAR Electroforming to serve your product needs. The C-9 Cast 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 cast surfaces is required.

I was sent the GAR S-22 comparator. Big bummer. Not only do I already have this, but I needed the C-9 for a specific date and now I missed my chance.Images and title are wrong.
