Overview

GAOTek high-precision roughness instrument using needle drawing method, needle method, also known as touch-pin method. When the stylus directly across the measured surface of the workpiece across the light, due to the measured surface profile of the ups and downs, the stylus will be perpendicular to the measured surface in the direction of the surface to produce up and down movement, the movement of the signal through the electronic device Amplified, and then through the instrument or other output device will be related to the roughness of the data or graphics output.
