1) GENERAL
The Phase II model no. SRG ‐ 2000 Mini Surface Roughness Tester is a next generation of
product developed for the Phase II Metrology Group that features high accuracy, a wide
range of application, simple operation and stable performance. It is widely applicable in
testing surfaces of all kinds of metals and non‐metals. Integrating the sensor with its
mainframe, its a hand‐held set especially suited for use on any production site.
2) WORKING PRINCIPLE AND STRUCTURE FEATURES
2.1) WORKING PRINCIPLE
When the motorized sensor is making a linear uniform motion along the test surface, the
contact stylus being perpendicular to the work surface, moves up and down with the work
surface. Its motion is converted into electric signals, which are amplified, filtered and
transformed into digital signals through a/d. The signals are then processed by the CPU
into Ra and Rz values before being displayed on the screen.
