It covers a measurement range up to 127 mm (5 inches minimum to 6 inches maximum) and delivers a resolution of 0.0001 decimal inches with an accuracy of 0.00015 decimal inches. The measuring faces are micro-lapped carbide, providing a hard, wear-resistant contact surface suited to repeated use in shop environments. A friction thimble gives the user consistent measuring pressure, and a ring-style lock nut holds the spindle position for readout transfer. A CR2450 battery is included.\u003c\/p\u003e\u003cp\u003eThis micrometer is used in precision machining shops, tool rooms, and quality-assurance settings where outside diameter or thickness measurements in the 5-to-6-inch range must be verified to sub-thousandth tolerances. It is appropriate for machinists, toolmakers, metrology technicians, and quality inspectors working to tight blueprint tolerances on shafts, bores, tooling, or finished components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eResolution of 0.0001 decimal inches for sub-thousandth readout\u003c\/li\u003e\n\u003cli\u003eAccuracy of 0.00015 decimal inches across the full range\u003c\/li\u003e\n\u003cli\u003eMicro-lapped carbide measuring faces resist wear and maintain flatness over time\u003c\/li\u003e\n\u003cli\u003eFriction thimble provides repeatable, consistent measuring force\u003c\/li\u003e\n\u003cli\u003eRing lock nut secures the spindle for stable readings\u003c\/li\u003e\n\u003cli\u003eBlack wrinkle and satin chrome finish; CR2450 battery included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard outside micrometer for general outside-dimension measurement in the 127 mm range; compatible with any application requiring a 5-to-6-inch electronic outside micrometer with a standard thimble-style interface.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eOutside micrometers require no installation but should be calibrated against a certified gauge block or standard before first use and at regular intervals. Store in the provided case away from temperature extremes and magnetic fields that can affect the electronic readout. Battery replacement uses a standard CR2450 cell; follow proper electrostatic-discharge precautions when opening the battery compartment. Clean measuring faces with a lint-free cloth before and after use to maintain accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMicrometer Type\u003c\/strong\u003e: Standard Outside\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 127 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 0.0001 decimal inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy (Decimal Inch)\u003c\/strong\u003e: 0.00015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy (mm)\u003c\/strong\u003e: 0.0040 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasuring Face Material\u003c\/strong\u003e: Micro-Lapped Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Friction\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLock Nut Type\u003c\/strong\u003e: Ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Wrinkle; Satin Chrome\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery\u003c\/strong\u003e: CR2450 (included)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 3.7 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 8.6 inches x 14.8 inches x 2 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12273\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51538263212338,"sku":"12273","price":744.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ca7864022cf9ba8d9cd08f5a59ce61a2.jpg?v=1785821194","url":"https:\/\/voomisupply.com\/products\/starrett-12273-electronic-outside-micrometer-127-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
