The nosepiece attaches to the tester's probe drive unit and positions the stylus correctly against flat workpiece surfaces during roughness measurement. It is a direct OEM-style replacement or supplemental accessory for shops and field technicians who require accurate, repeatable surface texture readings on flat parts. Metrology technicians, quality control inspectors, and precision machining professionals install this component as part of routine instrument setup or probe configuration changes.\u003c\/p\u003e\n\u003cp\u003eThis nosepiece is intended for flat surface measurement applications on the SJ-301\/R Surftest portable surface roughness tester. Typical use cases include incoming inspection, in-process quality checks on machined flat surfaces, and final surface finish verification on components such as plates, flanges, and ground or milled faces. It is used in manufacturing, tool and die, aerospace, and general metrology environments where portable surface finish testing is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlat surface geometry positions the stylus for accurate measurement on planar workpieces\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for use with the SJ-301\/R Surftest portable surface roughness tester\u003c\/li\u003e\n  \u003cli\u003eOEM accessory ensuring proper fit and measurement integrity\u003c\/li\u003e\n  \u003cli\u003eCompact, single-unit packaging suited for bench and field use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the MITUTOYO SJ-301\/R Surftest portable surface roughness tester, as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified metrology technician or instrument operator familiar with the SJ-301\/R tester. Power down or disable the instrument before attaching or removing the nosepiece to avoid stylus damage. Handle the stylus assembly with care during nosepiece changes, as the stylus tip is precision-ground and susceptible to damage from contact or impact. Follow the instrument manufacturer's procedure for nosepiece attachment and verify stylus seating before resuming measurements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccessory Type\u003c\/strong\u003e: Flat Surface Nosepiece\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: SJ-301\/R 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: 12AAA217\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51558465732914,"sku":"12AAA217","price":258.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/85168bac89839191f66f31d0054fb9b7.jpg?v=1786413014","url":"https:\/\/voomisupply.com\/products\/mitutoyo-12aaa217-flat-surface-nosepiece-sj-301-r","provider":"Voomi Supply","version":"1.0","type":"link"}
