Description
Overview
GAOTek surface roughness measuring instrument is a handheld instrument suitable for on-site and mobile measurement. It can measure a variety of machined parts, is capable of evaluating surface textures with a variety of parameters according to various international standards. The measurement results are displayed digitally/graphically on the color graphic LCD display.
