The standard measures 13 inches in length and delivers accuracy up to 0.000250 inches, making it suitable for high-tolerance inspection work. It includes a heat insulating handle to prevent thermal expansion from hand contact during use, which helps maintain measurement integrity. Calibration standards like this one are used by quality control technicians, tool room machinists, and metrology professionals who need traceable reference points for their measuring instruments.\u003c\/p\u003e\n\u003cp\u003eThis calibration standard is used in machine shops, inspection labs, and manufacturing environments where micrometer accuracy must be verified at regular intervals. The spherical end geometry provides consistent contact geometry for repeatable reference measurements. Its 13-inch length accommodates larger-range outside micrometers commonly found in production and inspection settings. The included heat insulating handle allows the technician to hold the standard without transferring body heat to the bar, which is critical when working to sub-thousandth tolerances.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAccuracy up to 0.000250 inches for reliable high-precision calibration reference\u003c\/li\u003e\n  \u003cli\u003eSpherical end geometry ensures consistent and repeatable contact with micrometer anvils\u003c\/li\u003e\n  \u003cli\u003e13-inch total length accommodates larger-range outside micrometers\u003c\/li\u003e\n  \u003cli\u003eIncludes heat insulating handle to minimize thermal error during use\u003c\/li\u003e\n  \u003cli\u003ePre-calibrated from the factory for immediate use in inspection or tool room settings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with outside micrometers requiring a 13-inch calibration reference standard with spherical end contact.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCalibration standards should be handled only by the insulating handle to prevent thermal growth from affecting measurement accuracy. Store the standard in its case when not in use and allow it to reach ambient temperature before taking reference measurements. Calibration intervals should follow the facility quality plan or applicable metrology standards. If the standard shows signs of wear, nicks, or damage on the contact surfaces, remove it from service and have it re-certified or replaced.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Length\u003c\/strong\u003e: 13 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.000250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Spherical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCalibrated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes Heat Insulating Handle\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: Micrometers\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: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MS160712013\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51721893708082,"sku":"MS160712013","price":77.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2d1e6d6eaa175ae6e5f1b493cc278a1.jpg?v=1788582707","url":"https:\/\/voomisupply.com\/products\/spi-ms160712013-micrometer-calibration-standard-13-in","provider":"Voomi Supply","version":"1.0","type":"link"}
