Each piece in the set serves as a precision reference standard for verifying and calibrating outside micrometers. The set is factory calibrated, giving technicians and tool-room professionals a traceable baseline for confirming instrument accuracy. At 13 pounds total, the set is substantial and intended for bench use in tool rooms, metrology labs, and quality control environments where measurement integrity is critical.\u003c\/p\u003e\u003cp\u003eThis calibration standard set is designed for use with outside micrometers in industrial, manufacturing, and precision machining environments. It covers the 12-inch to 23-inch range in individual increments, making it suitable for shops that regularly work with large-bore or large-diameter components and need reliable go\/no-go reference points for their measurement tools. Calibration standard sets like this one are typically used by tool room technicians, quality engineers, and metrology personnel performing routine instrument checks or pre-job verification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e12-piece set covering 12 to 23 inches in individual length increments\u003c\/li\u003e\n\u003cli\u003eFactory calibrated for traceable measurement accuracy\u003c\/li\u003e\n\u003cli\u003eDesigned specifically for use with outside micrometers\u003c\/li\u003e\n\u003cli\u003eMinimum length of 12 inches suits large-scale precision measurement applications\u003c\/li\u003e\n\u003cli\u003eSet weight of 13 pounds reflects solid, full-length construction suitable for bench use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with outside micrometers requiring calibration standards in the 12 to 23 inch measurement range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCalibration standards should be handled with care to avoid surface damage that could affect reference accuracy. Use a clean, stable work surface when performing micrometer verification. Store standards in their protective case when not in use to prevent corrosion or contact damage. Calibration procedures should follow the instrument manufacturer guidelines and applicable metrology standards for your facility.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Length\u003c\/strong\u003e: 23 inches\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 13 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 64146\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542309208370,"sku":"64146","price":1778.19,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a64c09e06a80498585f66692544052b7.jpg?v=1785897675","url":"https:\/\/voomisupply.com\/products\/starrett-64146-micrometer-calibration-standard-set","provider":"Voomi Supply","version":"1.0","type":"link"}
