It covers a measurement range of 0 to 1.00 inch with a resolution of 0.0001 inch and an accuracy of 0.0001 inch, making it suitable for quality control and inspection work in manufacturing and mechanical trades. The micrometer features a carbide anvil for wear resistance, a ratchet thimble for consistent measuring pressure, and a positive lock nut to hold readings securely. It is calibrated to ASME B89.1.13 standards and weighs 0.85 pounds.\u003c\/p\u003e\u003cp\u003eThis instrument is used in precision measurement applications where standard flat-anvil micrometers cannot access tube walls or similar curved or hollow workpieces. Typical users include machinists, quality control technicians, and tool room personnel working in manufacturing, aerospace, automotive, and industrial maintenance environments. The rotating spindle and ratchet thimble allow repeatable measurements across multiple operators. The unit ships in a plastic storage box for protection and safe transport.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eElectronic readout with 0.0001 inch resolution for precise measurements\u003c\/li\u003e\n\u003cli\u003eCarbide anvil resists wear during repeated use on hard materials\u003c\/li\u003e\n\u003cli\u003eRatchet thimble provides consistent and repeatable measuring force\u003c\/li\u003e\n\u003cli\u003ePositive lock nut secures the spindle position to hold readings\u003c\/li\u003e\n\u003cli\u003eRotating spindle design accommodates tube and hollow workpiece geometry\u003c\/li\u003e\n\u003cli\u003eCalibrated to ASME B89.1.13 standards; includes plastic storage box\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style precision measuring instrument suitable for general tube wall thickness measurement applications in quality control and machine shop environments.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTube micrometers are handled and used by machinists and quality control technicians; no power shutoff is required, but the instrument should be zeroed and verified against a known standard before use. Store the micrometer in its included plastic box when not in use to protect the anvil and spindle surfaces. Do not exceed the rated measurement range, and clean contact surfaces before each use to ensure accurate readings.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0 to 1.00 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 0.0001 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0001 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 0.0001 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Electronic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnvil Type\u003c\/strong\u003e: Tube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnvil Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpindle Material\u003c\/strong\u003e: SUS420F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLock Nut Type\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpindle Diameter\u003c\/strong\u003e: 6.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThroat Depth\u003c\/strong\u003e: 24 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 3.50 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCalibrated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B89.1.13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 7.0 inches (L) x 3.4 inches (W) x 0.97 inches (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.85 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Plastic storage box\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: CMS220519019\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51689854566706,"sku":"CMS220519019","price":264.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a69c8231af292250a87778f63dbb8ec.jpg?v=1788264767","url":"https:\/\/voomisupply.com\/products\/spi-cms220519019-electronic-tube-micrometer-0-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
