It provides 8 reference patches spanning Ra 0.025–3.2 µm (1–125 µin), roughness grades N1–N8. Machinists and inspectors use it to compare a cylindrical grinding finish directly against known roughness values. A lightweight Microsurf equivalent (316) is offered for office and design use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMachining method: Cylindrical Grinding\u003c\/li\u003e\n\u003cli\u003eNumber of patches: 8\u003c\/li\u003e\n\u003cli\u003eRa 0.025–3.2 µm \/ 1–125 µin\u003c\/li\u003e\n\u003cli\u003eRoughness grades N1–N8\u003c\/li\u003e\n\u003cli\u003eHeavy-duty Series 100 construction for workshop use\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Rubert","offers":[{"title":"Default Title","offer_id":67656278671473,"sku":"116","price":0.0,"currency_code":"AED","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0625\/3930\/0977\/files\/100-series-comparators_7e21e0c7-7ef9-45d8-83c3-e588d4e0c58f.jpg?v=1791811237","url":"https:\/\/www.generaltechshop.sa\/products\/rubert-116-series-100-roughness-comparator-cylindrical-grinding-ra-0-025-3-2-m-n1-n8-8-patches","provider":"General Tech Services LLC","version":"1.0","type":"link"}
