We are engaged in manufacturing a comprehensive range of surface roughness tester that is acknowledged for its features like accuracy in measurement and durability. These pocket-size & economically priced equipment is manufactured utilizing high grade raw material, to make these in compliance with ISO and DIN standards. Our range is used for measuring a varied range that is suitable for most material, especially flat, outer cylinder and sloping surface material. This tester Feature external calibration at keyboard with both Ra and Rz parameters in one instrument. Available with rechargeable batteries and can work while charging, these are available in competitive prices.

C9 Casting Micro Finish Surface Comparator
Place the Micro Finish 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.
The original masters and the electro formed replica production masters have been checked at evenly distributed intervals. Sufficient measurements were taken to determine a representative average. The rating listed is the average of these readings.
The C-9 Cast Micro Finish Comparator Surface Roughness Scale is made by a dual electro forming process wherein nickel is electro deposited 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.
The C-9 Cast Microfinish Comparator Surface Roughness Scale provides an economical tool which permits roughness to be specified on the same basis as linear measurements. The surfaces presented are the result of years of research and engineering. Details covering this subject are now published in The American National Standards Institute (ANSI) specification titled: "Surface Texture, Surface Roughness, Waviness and Lay." ANSI/ASME B46.1
