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 M.MD measuring program to process the measuring data, easy for printing and filing

Technical highlights
No need to change sensors and needles; Simultaneous analysis of roughness and profilometer can be achieved at one time.
One measurement can analyze the roughness of different parts of the workpiece and improve the measuring efficiency.
The X-axis adopts friction linear guides, which feature high precision and long service lifeX-Z1
Z1 axis adopts imported digital sensor with high precision and good linearity
Simple stylus replacement, one time installation, no need correction
Software supports one-click switching between Chinese and English
Support winXP, win7 system
Software annotation is the same as CAD
Automatic Recognition of Arc and Line
Support DXF format file import and export, customize CAD format export
Support for continuous annotation, base annotation, and insert points randomly
Support graphic and coordinate free rotation
The original data can be saved automatically for multiple annotations.
Mirror function to save annotated files
The current position of X and Z1 axes can be observed.
Stylus automatic contact, lifting and return .
Indefinitely operation for Revoked and Restored
When the capture switch is turned on, it automatically generates and captures the characteristics of intersection point, circle center, line segment point, end point, arc intersection point, midpoint and tangent point.
Even in the case of non-proportional amplification, normal angle, arc, horizontal, vertical and linear labeling can be annotated normally.
