It features a ratchet thimble for consistent measuring force and a digital counter for direct readout, reducing the chance of misreading the thimble scale. Both the anvil and spindle are carbide-tipped for wear resistance in production and inspection environments. The unit ships with a calibration certificate traceable to NIST standards, making it ready for use in quality-controlled settings without additional calibration steps.\u003c\/p\u003e\u003cp\u003eThis micrometer is suited for dimensional inspection of cylindrical bores, radiused surfaces, tubing walls, and other curved features where a spherical anvil face is required to establish a well-defined contact point. It is used in machine shops, manufacturing quality departments, and precision measurement labs. The included case protects the instrument during storage and transport. It is intended for installation and use by machinists, metrology technicians, and quality control personnel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpherical anvil face provides accurate contact on curved and contoured surfaces\u003c\/li\u003e\n\u003cli\u003eRatchet thimble delivers repeatable, consistent measuring force\u003c\/li\u003e\n\u003cli\u003eDigital counter enables direct, easy-to-read measurement output\u003c\/li\u003e\n\u003cli\u003eCarbide anvil and spindle materials resist wear for long service life\u003c\/li\u003e\n\u003cli\u003eNIST-traceable calibration certificate and case included\u003c\/li\u003e\n\u003cli\u003eNon-rotating spindle design preserves workpiece surface integrity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style precision measuring instrument for use in general dimensional inspection applications requiring a spherical anvil contact face.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSpherical face micrometers are used by metrology technicians and machinists and require no permanent installation. Before use, verify the instrument calibration against a known standard and inspect the carbide faces for damage. Store in the provided case when not in use to prevent damage to the measuring faces. Handle measuring surfaces with care and avoid dropping the instrument, as impact can affect calibration and accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Mechanical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnvil Type\u003c\/strong\u003e: Spherical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDigital Counter\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotating Spindle\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eData Output\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.00015 inches\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: Carbide\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\u003eIncludes\u003c\/strong\u003e: Case, Certificate of Calibration\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: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 295-253CAL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51563517706546,"sku":"295-253CAL","price":341.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9a896a8704539f76d463414db1cc3c3b.jpg?v=1786498659","url":"https:\/\/voomisupply.com\/products\/mitutoyo-295-253cal-spherical-face-micrometer-nist-cal","provider":"Voomi Supply","version":"1.0","type":"link"}
