30 Piece Surface Roughness Standards Set With Ra 0.05 To 12.5um Comparators For Quick No Fuss Roughness Testing And Gauge Calibration In Manufacturing

30-Piece Surface Roughness Standards for Ra Comparisons
✔️ 30-piece set with Ra 0.05-12.5 μm comparators for quick checks

These surface roughness standards are designed for quick, on-site comparison of finish quality on manufactured parts, commonly used on production floors and in quality-control labs. Manufactured from solid electroformed nickel, they provide stable references for gauge calibration and finish checks. Marked in AA (micro inches) and Ra (microns) metric units and manufactured to ANSI-B-46.1-1985 standards. Color: white.
