SRT-680G Roughness and Contour Tester
Measurement Principle
● Cartesian coordinates, stylus contacts.
● High precision air floating guide rail –As the measuring datum of
X coordinate to guarantee the linear moving accuracy in X
direction.
● High precision digital sensor – to get signal of Z coordinate for
measuring the profile of various precise mechanical piece part.
● Computer and windows-based measuring program to process the
measuring data, easy for printing and filing
