It covers a range of 0 to 0.06 inches with a graduation of 0.0005 inches per division, allowing resolution fine enough for close-tolerance work. Accuracy is rated at 0.0012 inches. The indicator uses a jeweled bearing movement for consistent, low-friction operation and mounts via a standard dovetail fitting compatible with common indicator holders and magnetic bases. A NIST-traceable short-form calibration certificate is included, supporting documentation requirements for regulated inspection environments.\u003c\/p\u003e\n\u003cp\u003eThis indicator is suited for machine shop inspection, surface plate work, fixture setup, and in-process measurement on mills, lathes, and grinding equipment. The 0-15-0 bidirectional dial scale with a 1.5-inch white dial face makes readings straightforward during both push and pull contact movement. The 210-degree contact point swivel angle provides access in tight or angled setups. A revolution counter tracks cumulative travel, and the rotating dial bezel allows zeroing at any contact position. Typical installers include machinists, quality technicians, and metrology professionals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0 to 0.06 inch measurement range with 0.0005 inch graduation per division\u003c\/li\u003e\n  \u003cli\u003eAccuracy rated at 0.0012 inches for close-tolerance inspection work\u003c\/li\u003e\n  \u003cli\u003eJeweled bearing movement reduces friction and wear for repeatable readings\u003c\/li\u003e\n  \u003cli\u003eDovetail mount is compatible with standard indicator holders and magnetic base arms\u003c\/li\u003e\n  \u003cli\u003e210-degree contact point swivel angle for access in confined or angled setups\u003c\/li\u003e\n  \u003cli\u003eNIST-traceable short-form calibration certificate included for documentation compliance\u003c\/li\u003e\n  \u003cli\u003eRotating dial bezel and revolution counter for versatile use across multiple measurement passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a dovetail-mount vertical dial test indicator for use with standard indicator holders, magnetic base arms, and surface plate fixtures common in machine shop and inspection environments.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the dovetail shank firmly in the holder before taking measurements to prevent movement that would affect accuracy. Contact point should be positioned perpendicular to the measured surface whenever possible to minimize cosine error. Avoid overtightening the clamping screw on the dovetail mount, as this can distort the shank and affect dial repeatability. Handle the instrument carefully to protect the jeweled movement from shock or impact.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0 to 0.06 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 0.0005 inches per division\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0012 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Reading\u003c\/strong\u003e: 0-15-0 bidirectional\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndicator Style\u003c\/strong\u003e: Vertical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: Jeweled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Dovetail\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Swivel Angle\u003c\/strong\u003e: 210 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Length\u003c\/strong\u003e: 0.86 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.079 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRange Per Revolution\u003c\/strong\u003e: 0.06 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCalibrated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTraceability Certification\u003c\/strong\u003e: NIST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContents\u003c\/strong\u003e: Short Form Certificate of Calibration\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5 inches (L) x 2.84 inches (W) x 1.78 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 21-532-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51784162771250,"sku":"21-532-7","price":175.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/afb62f114b449a536dcec1cbe72519f2.jpg?v=1789198200","url":"https:\/\/voomisupply.com\/products\/spi-21-532-7-vertical-dial-test-indicator-0-06-in","provider":"Voomi Supply","version":"1.0","type":"link"}
