Rubert 128 | Series 100 Roughness Comparator – Vertical Grinding | Ra 0.2–6.4 µm, N4–N9, 6 Patches
With 6 patches covering Ra 0.2–6.4 µm (8–250 µin), roughness grades N4–N9, the Rubert 128 gives a workshop reference for vertically ground surfaces. It is part of the Series 100 line, the heavy-duty comparators made for shop-floor use, and lets operators check a vertical grinding finish against reference roughness values. A lightweight Microsurf equivalent (328) is offered for office and design use.
