It delivers a maximum range of 9 inches with a graduation of 0.0001 inches and an accuracy of 0.0002 inches, making it suitable for close-tolerance inspection work. The ratchet stop thimble provides consistent measuring pressure, and the rotating spindle allows smooth, repeatable contact with the workpiece. Solid carbide measuring faces resist wear over high-cycle use. The unit ships calibrated with NIST traceability certification, documentation, and a protective case included. Machinists, quality control technicians, and toolroom professionals are the primary users of this instrument.\u003c\/p\u003e\n\u003cp\u003eThis micrometer is suited for dimensional inspection of large-diameter shafts, bores, and machined components where a 9-inch measurement range is required. It is appropriate for both production-floor spot checks and toolroom inspection setups. The included short-form certificate of calibration and NIST traceability standards documentation supports use in environments where measurement traceability is required for quality audits or process control records.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9-inch maximum measurement range for large-workpiece inspection\u003c\/li\u003e\n  \u003cli\u003e0.0001-inch graduation with 0.0002-inch accuracy for close-tolerance readings\u003c\/li\u003e\n  \u003cli\u003eRatchet stop thimble delivers consistent, repeatable measuring pressure\u003c\/li\u003e\n  \u003cli\u003eSolid carbide measuring faces extend service life under frequent use\u003c\/li\u003e\n  \u003cli\u003eNIST traceability certification and short-form calibration certificate included\u003c\/li\u003e\n  \u003cli\u003eHammertone and baked enamel coating for corrosion and impact resistance\u003c\/li\u003e\n  \u003cli\u003eIncludes protective carrying case and supporting standards documentation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standalone mechanical outside micrometer for general-purpose dimensional inspection of external surfaces up to 9 inches in diameter or thickness.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis instrument does not require installation, but proper handling procedures apply. Store the micrometer in its included case when not in use to protect the measuring faces and calibration. Allow the micrometer and workpiece to reach the same ambient temperature before measuring to reduce thermal expansion errors. Do not overtighten the spindle against the workpiece; use the ratchet stop exclusively to apply measuring force. Recalibrate on a scheduled interval per your facility quality program or applicable metrology standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement Range\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 0.0001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet Stop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRotating Spindle\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Face Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCalibrated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTraceability Certification\u003c\/strong\u003e: NIST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Hammertone; Baked Enamel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Case, Short Form Certificate of Calibration, Standards Documentation\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 16.46 inches (L) x 10.32 inches (W) x 1.46 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.56 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111601\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: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MS1536-04\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51700174225714,"sku":"MS1536-04","price":130.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c8e5617801d7b274dc30dd6902a9001e.jpg?v=1788387150","url":"https:\/\/voomisupply.com\/products\/spi-ms1536-04-outside-micrometer-9-in-ratchet-stop-nist","provider":"Voomi Supply","version":"1.0","type":"link"}
