SRT110 Digital Surface roughness tester, Portable surface
roughness gage, Surface testing machine
Introduction
SRT110 has the features of high accuracy, wide measuring range, easy to operate, portable,
working stably features. It is widely used at inspecting the processing surface of many kinds of
metals and non-metal.
Features
Optimized electric circuit design with transducer structure design, high integrate power, driver
and display. Select freely with Ra,Rz,Rq,Rt parameters. It could test excircle, flat surface, conical
surface and also test groove with length and width larger than 80*30mm.
Functions
