Rubert 331 | Microsurf Roughness Comparator – Spark Erosion (EDM) | Ra 0.4–50.0 µm, Rz 2.5–160 µm, N5–N12

Part Number : 331

Intended for spark-eroded (EDM) surfaces, the Rubert 331 is a lightweight Microsurf (300 series) plate aimed at designers and office staff. Its 8 patches span Ra 0.4–50.0 µm and Rz 2.5–160 µm, roughness grades N5–N12, so both Ra and Rz can be read for each patch. It is supplied in a plastic wallet with an instruction card. For workshop use, the heavy-duty Series 100 equivalent is the 131.
