The kit includes a centering indicator and a stationary face indicator, giving technicians two instrument types in a single fitted case. Measuring range extends to 2.5 inches (63.50 mm), with a dial graduation of 0.01 mm and an accuracy of 0.005 mm (0.0002 inches). The 0-25-0 dial reading format with a yellow dial face allows for quick bidirectional readings. Contact point shanks measure 1\/8 inch (3.18 mm) in diameter, and the included ball-tip feelers have a 0.130-inch ball diameter.\u003c\/p\u003e\u003cp\u003eThis kit is suited for use in machine shops, tool rooms, and quality control environments where both centering and surface runout checks are performed. The set covers a range of contact point lengths - 2 inches, 4 inches, and 6 inches - accommodating various reach requirements on mills, lathes, surface plates, and inspection fixtures. The fitted case keeps all components organized and protected between uses, making it practical for bench or field inspection work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2.5-inch (63.50 mm) measuring range with 0-25-0 bidirectional dial reading\u003c\/li\u003e\n\u003cli\u003eAccuracy of 0.005 mm (0.0002 inches) for high-precision inspection tasks\u003c\/li\u003e\n\u003cli\u003eIncludes both a centering indicator and a stationary face indicator\u003c\/li\u003e\n\u003cli\u003eThree external feelers and three internal feelers for versatile contact configurations\u003c\/li\u003e\n\u003cli\u003eContact point lengths of 2 inches, 4 inches, and 6 inches included\u003c\/li\u003e\n\u003cli\u003e0.130-inch ball diameter tip; 1\/8-inch shank diameter for standard collet compatibility\u003c\/li\u003e\n\u003cli\u003eYellow dial face with 40 mm dial diameter for clear readability\u003c\/li\u003e\n\u003cli\u003eFitted carrying and storage case included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose dial test indicator kit compatible with standard 1\/8-inch indicator holders, magnetic bases, and test stands used in machine shop and inspection environments.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and setup should be performed by a qualified machinist or metrology technician. Secure the indicator shank firmly in a compatible 1\/8-inch collet or indicator holder before use, and verify zero before taking measurements. Avoid side-loading the contact tip beyond the indicator's designed contact angle range, as this can affect accuracy and damage the mechanism. Store all feelers and accessories in the fitted case when not in use to protect contact surfaces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasuring Range\u003c\/strong\u003e: 2.5 inches (63.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Reading\u003c\/strong\u003e: 0-25-0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.005 mm (0.0002 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Graduation\u003c\/strong\u003e: 0.01 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 40 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Color\u003c\/strong\u003e: Yellow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.130 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Point Lengths\u003c\/strong\u003e: 2 inches, 4 inches, 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (3.18 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Type\u003c\/strong\u003e: Dial Test Indicator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: 3 External Feelers, 3 Internal Feelers, Center Point Feeler, Centering Indicator, Stationary Face Indicator, Restraining Arm, Fitted Case\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\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: 13-979-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51692791562546,"sku":"13-979-0","price":272.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c88d1f6ff58966c638cc233a92bf152c.jpg?v=1788302970","url":"https:\/\/voomisupply.com\/products\/spi-13-979-0-dial-test-indicator-kit-9-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
