Measuring 19 inches in length, this calibration bar delivers accuracy up to 0.0002 inch, making it suitable for precision measurement environments where tight tolerances are critical. The unit arrives pre-calibrated and includes a heat insulating handle that prevents thermal expansion errors caused by hand contact during use. Licensed metrologists, quality control technicians, and tool room machinists rely on calibration standards like this to maintain measurement traceability and tool reliability.\u003c\/p\u003e\n\u003cp\u003eThis calibration standard is intended for use with outside micrometers in shop floor, tool room, and laboratory settings. Its 19-inch length makes it appropriate for calibrating larger-range micrometers used in heavy machining, aerospace, and precision manufacturing environments. The spherical end geometry ensures consistent, repeatable contact points during calibration, reducing operator-induced measurement variation. The included heat insulating handle is a practical feature for bench use where the standard must be held for extended periods.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e19-inch overall length accommodates larger micrometer calibration ranges\u003c\/li\u003e\n  \u003cli\u003eAccuracy up to 0.0002 inch for precise verification work\u003c\/li\u003e\n  \u003cli\u003eSpherical end design provides consistent, repeatable contact geometry\u003c\/li\u003e\n  \u003cli\u003ePre-calibrated and ready for immediate use\u003c\/li\u003e\n  \u003cli\u003eIncludes heat insulating handle to minimize thermal expansion error during handling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with outside micrometers.

Always allow the standard to acclimate to the ambient temperature of the measurement environment before use to minimize thermal expansion effects. Use the included heat insulating handle when holding the standard during calibration to avoid introducing body heat into the bar. Store in the supplied case or a clean, protected environment when not in use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Length\u003c\/strong\u003e: 19 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0002 inch\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\u003eHeat Insulating Handle Included\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: 2.9 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: MS160712019\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51704032133426,"sku":"MS160712019","price":106.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/43313e87dd6369a6d741cd43ef83de69.jpg?v=1788420175","url":"https:\/\/voomisupply.com\/products\/spi-ms160712019-micrometer-calibration-standard-19-in","provider":"Voomi Supply","version":"1.0","type":"link"}
