Measuring 200mm in length, this calibration standard features spherical ends that provide repeatable point contact, reducing the risk of measurement error caused by surface irregularities. An integrated heat-insulating handle is included, helping to prevent thermal expansion from hand contact during calibration routines. Licensed metrologists, calibration technicians, and precision tool specialists rely on this type of reference standard to keep shop-floor and lab-grade micrometers within spec.\u003c\/p\u003e\n\u003cp\u003eThis calibration standard is suited for use in tool cribs, quality control labs, and precision machining environments where micrometer accuracy must be periodically verified. It is intended for use with standard outside micrometers and is particularly well suited to facilities that maintain formal calibration intervals or traceability programs. The 200mm length makes it appropriate for verifying mid-range micrometer spans in both production and inspection settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpherical ends provide consistent, repeatable contact point during micrometer verification\u003c\/li\u003e\n  \u003cli\u003e200mm reference length for mid-range micrometer calibration\u003c\/li\u003e\n  \u003cli\u003eAccuracy of 0.0032mm supports high-precision verification routines\u003c\/li\u003e\n  \u003cli\u003eIncludes heat-insulating handle to minimize thermal growth from hand contact\u003c\/li\u003e\n  \u003cli\u003eCompact and portable for use at the machine, bench, or inspection station\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style calibration reference for use with outside micrometers requiring a 200mm span verification standard.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCalibration standards should be handled only by qualified calibration or metrology personnel following established measurement procedures. Always allow the standard and the micrometer under test to thermalize to the same ambient temperature before use, and use the heat-insulating handle to avoid introducing thermal error. Store in the provided case or a controlled environment when not in use to protect reference surfaces from wear or contamination.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 200mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0032mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeat Insulating Handle Included\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 50984\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51543416504626,"sku":"50984","price":102.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b43e8acd954c3b917a937434f3b71ae_850be525-8796-418c-af49-021ab34ccaac.jpg?v=1785918340","url":"https:\/\/voomisupply.com\/products\/starrett-50984-micrometer-calibration-standard-200mm","provider":"Voomi Supply","version":"1.0","type":"link"}
