It covers a 1-inch measurement range using a single rotating rod and delivers accuracy to plus or minus 0.00015 inches, with a base flatness of 0.000050 inches. The ratchet stop thimble provides consistent measuring force, reducing operator-to-operator variation. Graduated at 0.0001 inches, it is suited for work where tight tolerances demand a reliable, hand-held depth-measuring instrument. This unit ships NIST certified with a traceability certification included, making it ready for use in controlled or documented quality environments.\u003c\/p\u003e\n\u003cp\u003eThis depth micrometer is used in precision machining shops, tool rooms, quality control labs, and maintenance environments where accurate depth readings are required on bores, slots, shoulders, and step features. The satin chrome finish reduces glare under shop lighting. With a 4.00 mm rod diameter and a single-rod configuration, it is appropriate for standard-depth applications in both production and inspection settings. Machinists, tool and die makers, and quality technicians are the primary users of this instrument.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-inch measurement range with 0.0001-inch graduation for high-resolution depth readings\u003c\/li\u003e\n  \u003cli\u003eRatchet stop thimble delivers consistent measuring force across repeated measurements\u003c\/li\u003e\n  \u003cli\u003eRotating rod design with 4.00 mm rod diameter for standard depth applications\u003c\/li\u003e\n  \u003cli\u003eAccuracy rated at plus or minus 0.00015 inches with base flatness of 0.000050 inches\u003c\/li\u003e\n  \u003cli\u003eSatin chrome finish minimizes glare in shop and inspection environments\u003c\/li\u003e\n  \u003cli\u003eNIST certified with traceability certification included, ready for documented quality programs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style mechanical depth micrometer for standard precision measurement applications requiring a 1-inch range and a single rotating rod configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis instrument should be handled and stored according to standard metrology practices. Before use, verify the reference surface and measuring rod are clean and free of debris to ensure accurate base contact. Calibration should be checked periodically against a known standard, and the included NIST traceability certification should be kept on file for quality documentation purposes. Avoid dropping or impacting the micrometer, as this can affect calibration and base flatness.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement Range\u003c\/strong\u003e: 1 inch\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: plus or minus 0.00015 inches (3 micrometers)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Flatness\u003c\/strong\u003e: 0.000050 inches\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: 4.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Rods\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet Stop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Satin Chrome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCalibration Standard\u003c\/strong\u003e: NIST Certified with Traceability Certification Included\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 8 inches L x 4.5 inches W x 1.5 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 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: MITUTOYO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 128-105CAL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51560889450802,"sku":"128-105CAL","price":224.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5051f556b18831a6e9249d0ab3e8ee9d.jpg?v=1786459165","url":"https:\/\/voomisupply.com\/products\/mitutoyo-128-105cal-mechanical-depth-micrometer-nist","provider":"Voomi Supply","version":"1.0","type":"link"}
