It covers a 225 mm measurement range with a 0.02 mm dial graduation, delivering an accuracy of 0.03 mm per reading. The caliper body and jaws are constructed from satin-chrome-finished stainless steel, providing corrosion resistance and durability under regular use. The yellow dial face on a black dial case provides high-contrast readability in varied lighting conditions. Machinists, millwrights, pipefitters, and maintenance technicians rely on this tool for inside, outside, depth, and step measurements in a single instrument.\u003c\/p\u003e\n\u003cp\u003eThe 64509 is suited for residential and commercial trade applications where metric measurement is required, including HVAC component sizing, plumbing fitting verification, and general mechanical maintenance. The 1.5-inch (38.10 mm) jaw length accommodates a wide range of workpiece geometries. The rack-and-gear drive mechanism and Starrett 120M measuring surfaces ensure consistent jaw travel and repeatable readings across the full 225 mm range. It ships as a single caliper with no additional accessories included.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e225 mm measurement range with 0.02 mm dial graduation for fine metric resolution\u003c\/li\u003e\n  \u003cli\u003eAccuracy rated at 0.03 mm across the full range\u003c\/li\u003e\n  \u003cli\u003eStainless steel body and jaws with satin chrome finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eYellow dial face on black case for high-contrast readability\u003c\/li\u003e\n  \u003cli\u003eMeasures outside, inside, depth, and step dimensions in one tool\u003c\/li\u003e\n  \u003cli\u003eRack-and-gear drive with Starrett 120M measuring surfaces for consistent jaw travel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose metric dial caliper suitable for trade and industrial measurement applications requiring a 225 mm range and 0.02 mm graduation resolution.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNo installation is required for this hand tool. Before use, verify the jaws close fully to a zero reading and adjust the bezel if needed to re-zero the dial. Keep measuring surfaces clean and free of debris to maintain accuracy. Store in a protective case away from moisture when not in use to preserve the stainless steel finish and dial mechanism.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement Range\u003c\/strong\u003e: 225 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Graduation\u003c\/strong\u003e: 0.02 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.03 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRange Per Revolution\u003c\/strong\u003e: 2 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBeam Graduation\u003c\/strong\u003e: 1 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJaw Length\u003c\/strong\u003e: 38.10 mm (1.5 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Types\u003c\/strong\u003e: Outside, Inside, Depth, Step\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJaw Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Satin Chrome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Face Color\u003c\/strong\u003e: Yellow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Case Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 64509\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540514373938,"sku":"64509","price":489.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ce7d1848a5cd12aa817452e18ff8f86f.jpg?v=1785857110","url":"https:\/\/voomisupply.com\/products\/starrett-64509-dial-caliper-225-mm-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
