Description

Overview

The GAOTek Surface Roughness Tester with Sampling Len (2 Way Charging) is designed to measure plane surface, canonical surface and cylindrical surface of various sampling length 0.25, 0.08 and 2.50. It has four parameters Ra, Rz, Rt and Rq with large measuring range. It adopts a high speed DSP processor for data processing which gives high accuracy in measurement and computation speed. Its aluminium mold design has the ability to resist electromagnetic interference. It offers 2 way charging either by special charger or USB port.
