DH – 9 VH / VHF Surface Roughness Meter
A truly versatile measuring system that delivers everything needed in both workshop and inspection settings. It supports straightforward roughness measurements directly on the machine—no accessories required, as well as more advanced applications in the measuring room using stands, special tracers, and other add‑ons, including contour measurement. The DIAVITE DH‑9 is designed specifically for use with tracers with skid. It provides maximum flexibility for comprehensive surface quality analysis. With optional PC software, it easily handles complex measurement tasks.
