Rubert 115 | Series 100 Roughness Comparator – Surface Grinding | Ra 0.025–3.2 µm, N1–N8, 8 Patches
The Rubert 115 is a Series 100 roughness comparator dedicated to surface-ground flat faces. Its 8 patches cover Ra 0.025–3.2 µm (1–125 µin), roughness grades N1–N8. Series 100 plates are the heavy-duty design intended for workshop use, so the 115 can be kept beside the machine for comparing parts with known reference finishes. A lightweight Microsurf equivalent (315) is offered for office and design use.
