Overview
Enviro Test Construct’s surface roughness tester with wide measurement range is designed to conform fully to international standards including ISO, DIN, JIS, and ANSI. This portable multi-purpose instrument evaluates the surface quality of parts across various parameters, offering roughness, waviness, and primary profile analysis. It supports measurements on planes, outer cylindrical surfaces, inner hole surfaces, and bearing channels. With a large measurement range, stable performance, and high accuracy, it is ideal for production sites, laboratories, and quality control facilities. The digital and graphical results are displayed on an industrial touch-screen pad, while data can also be transferred to a computer or printer for extended analysis.
