Built from cast iron, this level measures 12 inches in length and delivers a graduation sensitivity of 0.0005 inches per 10 inches, making it suitable for applications where tight flatness tolerances are required. The base flatness is held to 0.0002 inches, ensuring a reliable reference surface. Two vials are included for reading level in multiple orientations. This tool is used by machinists, metrology technicians, and precision mechanics performing equipment setup, surface plate inspection, and machine tool alignment.\u003c\/p\u003e\n\u003cp\u003eThis inspection block level is used in precision machining and industrial maintenance environments where surface flatness and machine alignment must be verified to tight tolerances. Typical applications include leveling machine tool bases, aligning milling machines and lathes, and verifying the flatness of surface plates and inspection fixtures. It is suited for both shop floor use and controlled metrology environments. The cast iron construction provides thermal stability and resistance to wear during repeated contact with machined surfaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGraduation sensitivity of 0.0005 inches per 10 inches for high-precision leveling\u003c\/li\u003e\n  \u003cli\u003eBase flatness held to 0.0002 inches for a stable, accurate reference surface\u003c\/li\u003e\n  \u003cli\u003e12-inch length accommodates a wide range of machine and surface plate applications\u003c\/li\u003e\n  \u003cli\u003eCast iron construction provides durability and thermal stability\u003c\/li\u003e\n  \u003cli\u003eTwo vials allow level readings in multiple orientations without repositioning\u003c\/li\u003e\n  \u003cli\u003e1-9\/16 inch base width for stable seating on machined surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style precision inspection tool for use on surface plates, machine tool beds, and other flat reference surfaces requiring high-sensitivity level measurement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of precision inspection levels is typically performed by machinists or metrology technicians. Before placing the level on any surface, clean both the base of the level and the reference surface thoroughly to remove chips, oils, or debris that could introduce measurement error. Handle the cast iron body carefully to avoid damage to the precision-ground base. Do not use this level as a straightedge or apply lateral force, as this can affect vial accuracy and base flatness over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLevel Type\u003c\/strong\u003e: Inspection Block\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1-9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation Sensitivity Per 10 Inches\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Flatness\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Vials\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.69 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: 61R-12\"-.0005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51698408456498,"sku":"61R-12\"-.0005","price":463.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0a78cda8d38ae629a0cc9d585c9afe4c.jpg?v=1788362390","url":"https:\/\/voomisupply.com\/products\/spi-61r-12-inches-0005-precision-inspection-block-level","provider":"Voomi Supply","version":"1.0","type":"link"}
