It delivers a 12-inch measurement range using a set of 12 interchangeable rotating rods, each with a 0.176-inch diameter. The ratchet stop thimble ensures consistent measuring pressure across readings, and a 0.001-inch graduation provides resolution suitable for close-tolerance work. The unit ships NIST certified, with a short-form certificate of calibration and a torque wrench included. Machinists, tool-and-die technicians, and quality control inspectors are the primary users of this instrument.\u003c\/p\u003e\n\u003cp\u003eThis depth micrometer is suited for measuring slot depths, counterbore depths, stepped surfaces, and other recessed features on metal workpieces. The 2.5-inch base length provides stable seating across a wide range of part geometries. With 12 rods covering the full 12-inch range, the instrument handles both shallow and deep measurements without needing a separate tool. It is appropriate for use in production shops, job shops, and inspection rooms where traceable calibration is required by a quality management system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12-inch total measurement range with 12 interchangeable rotating rods\u003c\/li\u003e\n  \u003cli\u003e0.001-inch graduation for fine-resolution depth readings\u003c\/li\u003e\n  \u003cli\u003eAccuracy of 0.00028 inches, meeting close-tolerance inspection requirements\u003c\/li\u003e\n  \u003cli\u003eRatchet stop thimble for repeatable, consistent measuring force\u003c\/li\u003e\n  \u003cli\u003e2.5-inch base length for stable contact across varied part surfaces\u003c\/li\u003e\n  \u003cli\u003eNIST certified with short-form certificate of calibration included\u003c\/li\u003e\n  \u003cli\u003eIncludes torque wrench and carrying case\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style depth micrometer for general machining and inspection use wherever a 12-inch range mechanical depth micrometer with rotating rods is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis instrument is a precision measuring tool and does not require installation in the traditional sense. Handle with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Store in the included case when not in use to protect the measuring faces and rods. Calibration should be verified periodically against a known reference surface per your facility quality procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.00028 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Rods\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRod Type\u003c\/strong\u003e: Rotating\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 0.176 inches (4.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet Stop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCalibration Standard\u003c\/strong\u003e: NIST Certified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Case, Short Form Certificate of Calibration, Torque Wrench\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 14.18 inches L x 8.08 inches W x 1.82 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.4 pounds\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: MS1536-06B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51699685753138,"sku":"MS1536-06B","price":433.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4b76e200e3fe7822ab94dd283c0f0b1a.jpg?v=1788379176","url":"https:\/\/voomisupply.com\/products\/spi-ms1536-06b-mechanical-depth-micrometer-12-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
