Measuring 12 inches in length, this reference bar provides a known dimension against which technicians can check micrometer spindle alignment and measurement accuracy. Calibrated to an accuracy of 0.00025 inches, it delivers the tight tolerance needed for precision measurement verification in tool rooms, calibration labs, and production environments. A heat insulating handle is included to prevent thermal expansion from body heat from affecting the reference measurement during use.\u003c\/p\u003e\n\u003cp\u003eThis calibration standard is used in metrology and quality control settings where outside micrometer accuracy must be confirmed before use on critical parts. It is suited for shops performing routine tool calibration, gauge certification programs, or incoming inspection workflows. Machinists, quality technicians, and calibration specialists working with large-range outside micrometers will find this standard appropriate for 12-inch measurement verification tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12-inch reference length for calibrating large-range outside micrometers\u003c\/li\u003e\n  \u003cli\u003eCalibrated accuracy to 0.00025 inches for tight tolerance verification\u003c\/li\u003e\n  \u003cli\u003eFlat end design for consistent, repeatable contact with micrometer anvil and spindle\u003c\/li\u003e\n  \u003cli\u003eIncludes heat insulating handle to minimize thermal expansion error during use\u003c\/li\u003e\n  \u003cli\u003eFactory calibrated — ready to use as a reference standard out of the package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with outside micrometers requiring a 12-inch calibration reference.

Always use the heat insulating handle when holding the standard to avoid transferring body heat to the bar, which can affect dimensional accuracy. Store the standard in its protective case when not in use to prevent surface damage to the reference faces. Follow your facility calibration procedures and any applicable ISO or ANSI gauge calibration standards when performing micrometer verification.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.00025 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCalibrated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeat Insulating Handle\u003c\/strong\u003e: Included\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 167-152\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51563700551986,"sku":"167-152","price":90.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/569838a34518c4f597a19c1636a64273.jpg?v=1786501734","url":"https:\/\/voomisupply.com\/products\/mitutoyo-167-152-micrometer-calibration-standard-12-in","provider":"Voomi Supply","version":"1.0","type":"link"}
