This accessory mounts the roughness gage detector to a magnetic stand, enabling stable, hands-free positioning during surface finish measurements. The adapter measures 0.315 inches in overall diameter and 0.315 inches in overall length, making it a compact interface component. It is installed by metrology technicians and quality control professionals working in machine shops, manufacturing facilities, and inspection labs where repeatable surface texture readings are required.\u003c\/p\u003e\u003cp\u003eThis adapter is used when a Surftest portable surface roughness tester must be held stationary on a magnetic stand rather than hand-held or bench-mounted. Typical applications include production floor inspection, incoming material verification, and comparative surface finish analysis on ferrous workpieces or fixturing. The small diameter allows the adapter to fit into standard magnetic stand collets or holders without modification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDesigned specifically for Mitutoyo Surftest portable surface roughness testers\u003c\/li\u003e\n\u003cli\u003eCompact 0.315-inch diameter fits standard magnetic stand collet holders\u003c\/li\u003e\n\u003cli\u003eEnables stable, hands-free detector positioning for repeatable measurements\u003c\/li\u003e\n\u003cli\u003eAccessory type: Magnetic Stand Adapter for direct gage-to-stand interface\u003c\/li\u003e\n\u003cli\u003ePackage quantity of 1 — sold as a single unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the Mitutoyo SJ-301 and SJ-210 Surftest portable surface roughness testers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by metrology or quality control technicians familiar with surface roughness measurement equipment. Before attaching or removing the adapter, ensure the roughness tester is powered off and the detector stylus is retracted or protected to prevent damage. Seat the adapter fully into the magnetic stand holder before energizing the magnet base. Follow the instrument manufacturer guidelines for stylus orientation and stand placement to avoid measurement error.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccessory Type\u003c\/strong\u003e: Magnetic Stand Adapter\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\u003eOverall Diameter\u003c\/strong\u003e: 0.315 inches (8.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.315 inches (8.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 12AAA221\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51560656077106,"sku":"12AAA221","price":89.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c11e275ee0d8d70ffd7b3aebac67402.jpg?v=1786455318","url":"https:\/\/voomisupply.com\/products\/mitutoyo-12aaa221-magnetic-stand-adapter-sj-301-sj-210","provider":"Voomi Supply","version":"1.0","type":"link"}
