Surface roughness gauge

Surface roughness instrument-Mitutoyo SJ

It is used for measure roughness of cylinder surface (ex: roller), roughness of flat (ex: extrusion die landing area), even including stepped, straightness, waviness can be gauged.

1.Thread surface, curved surface of tiny gap measure is available.

2.Excellent design with high resolution for precision measure.

3.It is with huge database, meet various countries roughness standard.

4.Measure range :800um (resolution: 0.000125um)

5.It is for measuring roughness of extrusion die.
