It covers a range of 0 to 6 inches with a graduation of 0.001 inches per division and a beam graduation of 0.1 inches per revolution, allowing technicians to take fast, accurate inside, outside, depth, and step measurements. The caliper body is constructed from Super Polymid, a durable engineering polymer that resists corrosion and reduces weight compared to steel alternatives. A shockproof measuring mechanism protects the dial from impact damage during regular shop use. The white dial face improves contrast and readability in low-light conditions. Net weight is 0.3 pounds.\u003c\/p\u003e\u003cp\u003eThis dial caliper is suited for use in HVAC, plumbing, electrical, and general mechanical trades where component dimensions, pipe OD, fitting clearances, or part tolerances need to be verified quickly. It is a practical bench or bag tool for technicians performing field measurements or equipment installation checks. The thumb wheel jaw adjustment allows controlled, single-hand positioning for repetitive measurements. With a 1.57-inch jaw length, it accommodates a wide range of workpiece profiles without repositioning.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0 to 6 inch measuring range with 0.001 inch graduation for precise readings\u003c\/li\u003e\n\u003cli\u003eSuper Polymid construction for corrosion resistance and reduced weight\u003c\/li\u003e\n\u003cli\u003eShockproof measuring mechanism protects dial during handling and transport\u003c\/li\u003e\n\u003cli\u003eWhite dial face with black and gray case for high-contrast readability\u003c\/li\u003e\n\u003cli\u003eThumb wheel jaw adjustment for controlled single-hand operation\u003c\/li\u003e\n\u003cli\u003e1.57 inch jaw length accommodates varied workpiece geometries\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose dial caliper for trade and shop measurement applications requiring a 0 to 6 inch range with 0.001 inch resolution.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eNo installation is required for this measuring tool. Before use, verify the jaws close fully to a zero reading and adjust the dial bezel if needed to null the indicator. Keep the measuring faces clean and free of debris to ensure accurate readings. Store in a protective case when not in use to prevent impact damage to the dial mechanism.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasuring Range\u003c\/strong\u003e: 0 to 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBeam Graduation\u003c\/strong\u003e: 0.1 inches per revolution\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJaw Length\u003c\/strong\u003e: 1.57 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJaw Adjustment Type\u003c\/strong\u003e: Thumb Wheel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliper Material\u003c\/strong\u003e: Super Polymid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Face Color\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Color\u003c\/strong\u003e: Black and Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeatures\u003c\/strong\u003e: Shockproof Measuring Mechanism\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: SPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 30-412-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51720555036978,"sku":"30-412-1","price":45.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/461c520bb89b389140f13621ff42bfad.jpg?v=1788566046","url":"https:\/\/voomisupply.com\/products\/spi-30-412-1-dial-caliper-0-6-inch-0-001-graduation","provider":"Voomi Supply","version":"1.0","type":"link"}
