This accessory mounts the roughness gage to a magnetic base stand, keeping the instrument securely positioned during measurement tasks on ferrous workpieces and machine surfaces. The adapter measures 9.53 mm in overall length with a 9.50 mm overall diameter, making it a compact, purpose-built interface between the instrument and the stand. Metrology technicians, toolroom machinists, and quality control personnel are the typical end users for this type of accessory.\u003c\/p\u003e\n\u003cp\u003eThis adapter is intended for shop-floor and laboratory environments where consistent, repeatable surface roughness measurements are required. It is suited for use in manufacturing quality assurance, precision machining inspection, and surface finish verification workflows. The compact size allows it to be used in tight fixture setups where direct hand-holding of the tester is impractical or introduces measurement error.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned specifically for Mitutoyo SJ-301 and SJ-210 Surftest portable surface roughness testers\u003c\/li\u003e\n  \u003cli\u003eEnables secure magnetic stand mounting for hands-free, stable gage positioning\u003c\/li\u003e\n  \u003cli\u003eCompact profile: 9.53 mm overall length and 9.50 mm overall diameter\u003c\/li\u003e\n  \u003cli\u003eOEM Mitutoyo accessory ensures proper fit without modification\u003c\/li\u003e\n  \u003cli\u003eSold individually — no additional hardware kit required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with the Mitutoyo SJ-301 and SJ-210 Surftest portable surface roughness testers.

Power down or switch off the surface roughness tester before attaching or removing stand accessories to avoid accidental stylus damage. Verify that the mating magnetic stand is rated for use with Surftest-series instruments before assembling. Handle the stylus assembly carefully during setup to prevent contact damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccessory Type\u003c\/strong\u003e: Magnetic Stand Adapter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9.53 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 9.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Instrument Type\u003c\/strong\u003e: Surftest Portable Surface Roughness Tester\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MITUTOYO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12AAA220\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51563185307954,"sku":"12AAA220","price":90.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/31ce4228e05132add9f9c4a84d148c42.jpg?v=1786492492","url":"https:\/\/voomisupply.com\/products\/mitutoyo-12aaa220-magnetic-stand-adapter-sj-301-sj-210","provider":"Voomi Supply","version":"1.0","type":"link"}
