The kit includes a dial indicator with fine adjustment and a magnetic base, giving technicians a complete setup for surface measurement, runout checks, and alignment tasks. The indicator reads from 0 to 0.001 inches with a resolution of 0.001 inches and a 0-100 dial scale. The magnetic base provides a secure, hands-free hold on ferrous surfaces, allowing for accurate, repeatable readings without additional fixturing. The assembly weighs 2 pounds and is suited for machine shops, fabrication environments, and field service work.\u003c\/p\u003e\u003cp\u003eThis kit is used in applications that require tight tolerance verification, including shaft alignment, surface flatness inspection, and machined-part qualification. The 3-inch magnetic base length and 6-inch arm length give the technician sufficient reach to position the indicator across a variety of workpiece configurations. The 7-inch post height and 1\/2-inch post diameter provide stable vertical extension. The 3\/8-inch clamping diameter accommodates standard indicator stems. Machinists, millwrights, pipefitters, and precision maintenance technicians are the primary users of this type of kit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDial indicator with fine adjustment included — ready to use out of the box\u003c\/li\u003e\n\u003cli\u003eMagnetic base with 3-inch base length for secure mounting on ferrous surfaces\u003c\/li\u003e\n\u003cli\u003eMeasurement range of 0 to 0.001 inches with 0.001-inch resolution\u003c\/li\u003e\n\u003cli\u003e6-inch arm length and 7-inch post height for flexible indicator positioning\u003c\/li\u003e\n\u003cli\u003e3\/8-inch clamping diameter fits standard indicator stems\u003c\/li\u003e\n\u003cli\u003e2-pound package weight for a portable, field-serviceable kit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose dial indicator base kit compatible with standard 3\/8-inch clamping diameter indicator stems and 0.400-inch rod diameter configurations typical of trade and industrial measurement applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMount the magnetic base on a clean, flat ferrous surface before activating the magnetic lock to ensure maximum holding force. Secure all arm and post joints firmly before zeroing the indicator to prevent drift during measurement. Machinists and maintenance technicians should verify that the workpiece and mounting surface are free of chips, oil film, or burrs that could affect base stability. Follow applicable shop safety procedures and power down any rotating equipment before taking contact measurements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndicator Type\u003c\/strong\u003e: Dial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0 to 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Graduation\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Reading\u003c\/strong\u003e: 0-100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 2.36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Style\u003c\/strong\u003e: Magnetic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArm Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePost Height\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePost Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamping Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 0.400 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRod Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Dial Indicator with Fine Adjustment\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: 25-372-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51711973392690,"sku":"25-372-4","price":98.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/50552d5e1f1d578b2106557d510aace9.jpg?v=1788482089","url":"https:\/\/voomisupply.com\/products\/spi-25-372-4-dial-indicator-base-kit-magnetic-base","provider":"Voomi Supply","version":"1.0","type":"link"}
