It measures up to 7 inches with a resolution of 0.000050 inches and an accuracy of 0.000200 inches, making it well-suited for close-tolerance inspection work. The carbide-tipped measuring face resists wear on hardened or abrasive workpiece surfaces. An IP54 dust- and splash-resistant rating protects the electronics during typical shop-floor use. A friction thimble provides consistent, repeatable seating force to eliminate operator-induced measurement error. Absolute and incremental measuring modes add flexibility for comparative gauging tasks. A NIST traceability certification is included, supporting quality system documentation requirements.\u003c\/p\u003e\n\u003cp\u003eThe MS170307005 is used in precision machining and manufacturing environments where external diameter, thickness, or step measurements must be verified to sub-thousandth-inch tolerances. The 3.75-inch throat depth allows access to workpieces with larger cross-sections. Typical users include machinists, quality technicians, and toolroom personnel performing first-article inspection, in-process gauging, or incoming material verification. The instrument ships with battery included, ready for immediate use on the bench or at the machine.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.000050-inch resolution for sub-thousandth-inch measurement readout\u003c\/li\u003e\n  \u003cli\u003e0.000200-inch accuracy with NIST traceability certification included\u003c\/li\u003e\n  \u003cli\u003eCarbide-tipped measuring face for extended wear life on hardened surfaces\u003c\/li\u003e\n  \u003cli\u003eIP54 rating provides protection against dust ingress and splash in shop environments\u003c\/li\u003e\n  \u003cli\u003eFriction thimble ensures consistent measuring force and repeatable results\u003c\/li\u003e\n  \u003cli\u003eAbsolute and incremental measuring modes supported\u003c\/li\u003e\n  \u003cli\u003eLR44 battery included; rotating spindle design\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose electronic outside micrometer for bench, toolroom, and shop-floor dimensional inspection applications requiring measurement up to 7 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCalibrated instruments should be handled and stored according to the manufacturer guidelines to maintain traceability. Allow the micrometer and workpiece to thermally stabilize to the same ambient temperature before taking critical measurements, as thermal expansion can affect readings at tight tolerances. Verify the zero setting against the supplied standard before use. Battery replacement uses an LR44 cell; always power the unit off before opening the battery compartment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 7.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 150.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 0.000050 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.000200 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThroat Depth\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Face Material\u003c\/strong\u003e: Carbide Tipped\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Friction\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Modes\u003c\/strong\u003e: Absolute and Incremental\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIP Rating\u003c\/strong\u003e: IP54\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRotating Spindle\u003c\/strong\u003e: Yes\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\u003eBattery Size\u003c\/strong\u003e: LR44 (included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 3.37 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 16.46 inches L x 10.32 inches W x 1.86 inches H\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: MS170307005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51720574533938,"sku":"MS170307005","price":357.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d187bb78a63fd58803c575bc1bf46999.jpg?v=1788566298","url":"https:\/\/voomisupply.com\/products\/spi-ms170307005-electronic-outside-micrometer-7in-ip54","provider":"Voomi Supply","version":"1.0","type":"link"}
