Machined to a maximum length of 3 inches with a calibrated accuracy of 0.000080 inches, this standard provides a reliable reference point for precision measurement tasks on the shop floor or in a calibration lab. It includes a heat insulating handle to prevent thermal expansion errors caused by hand contact, which is critical when working at this level of measurement precision. Metrology technicians, machinists, and quality control personnel use this type of standard as part of routine gage calibration and verification workflows.\u003c\/p\u003e\n\u003cp\u003eThis calibration standard is designed for use with outside micrometers in precision machining, manufacturing, and inspection environments. The flat end configuration makes it compatible with standard anvil and spindle face contact surfaces. It is well-suited for tool rooms, quality labs, and production floor gage stations where micrometers require periodic calibration checks or zero-setting before use. The included heat insulating handle supports stable, repeatable measurements regardless of ambient handling conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCalibrated flat end standard with a maximum length of 3 inches\u003c\/li\u003e\n  \u003cli\u003eAccuracy to 0.000080 inches for high-precision verification\u003c\/li\u003e\n  \u003cli\u003eFlat end shape compatible with standard micrometer anvil and spindle faces\u003c\/li\u003e\n  \u003cli\u003eIncludes heat insulating handle to minimize thermal expansion errors during handling\u003c\/li\u003e\n  \u003cli\u003eFactory calibrated for immediate use in gage verification routines\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with outside micrometers as a calibration and setting standard.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCalibration standards should be handled only by the insulating handle to avoid thermal growth from body heat, which can affect readings at sub-ten-thousandth accuracy levels. Store the standard in its case away from temperature extremes and keep contact faces clean and free of burrs or debris before use. Calibration work should be performed by a qualified metrology technician or machinist following applicable measurement standards and shop quality procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.000080 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Flat\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: 0.3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\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: MS160712003\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51715600613682,"sku":"MS160712003","price":17.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c6858c6b9925cbeebed27a565b0ded22.jpg?v=1788516172","url":"https:\/\/voomisupply.com\/products\/spi-ms160712003-micrometer-calibration-standard-3-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
