Rubert 334 | Microsurf Roughness Comparator – Castings | Ra 0.8–50.0 µm, Rz 2.5–250 µm, N6–N12
The Rubert 334 is a Microsurf comparator for as-cast surfaces. It carries 7 patches covering Ra 0.8–50.0 µm and Rz 2.5–250 µm, roughness grades N6–N12. Microsurf plates are the lightweight 300 series for office and design use, and each comes in a plastic wallet with an instruction card, making the 334 convenient for drawing offices specifying finishes. For workshop use, the heavy-duty Series 100 equivalent is the 134.
