It features a 0-25-0 balanced dial reading and a fine graduation of 0.0005 inches, making it suitable for detecting small surface variations and runout during part inspection. The flat back design allows the indicator to seat flush against magnetic bases, surface plates, and indicator holders. A built-in revolution counter helps the technician track total travel across multiple dial rotations, reducing read errors during longer measurements.\u003c\/p\u003e\u003cp\u003eThis dial drop indicator is used in machine shops, tool rooms, and production inspection environments. It is suited for tasks such as checking shaft runout, verifying part flatness, setting up workholding on mills and lathes, and confirming tolerance compliance on finished components. Machinists, toolmakers, and quality control inspectors are the primary users. The compact 1.5-inch dial diameter keeps the overall footprint manageable in tight setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0-25-0 balanced dial reading for bidirectional measurement\u003c\/li\u003e\n\u003cli\u003e0.0005 inch graduation for fine-resolution inspection work\u003c\/li\u003e\n\u003cli\u003e1.5 inch dial diameter with black dial face for high contrast readability\u003c\/li\u003e\n\u003cli\u003eFlat back design for flush mounting on magnetic bases and indicator stands\u003c\/li\u003e\n\u003cli\u003eRevolution counter tracks cumulative travel across multiple rotations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank dial drop indicator compatible with conventional indicator holders, magnetic base arms, and dial indicator fixtures that accept this style of drop indicator.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDial drop indicators are typically mounted and adjusted by machinists or inspection technicians using a magnetic base, indicator stand, or dedicated fixture. Before mounting, ensure the work surface and indicator contact point are clean and free of chips or debris. Do not overtighten the clamping collar on the indicator stem, as this can affect spindle movement and measurement accuracy. Follow shop calibration procedures and handle the indicator carefully to avoid dropping, which can damage the internal gear mechanism.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Reading\u003c\/strong\u003e: 0-25-0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Graduation\u003c\/strong\u003e: 0.0005 inches\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: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack Type\u003c\/strong\u003e: Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRevolution Counter\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: CDI#26103B-SPI\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51716709744946,"sku":"CDI#26103B-SPI","price":212.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ddbc36f909cc7d2970e161f264fc2b33.jpg?v=1788530713","url":"https:\/\/voomisupply.com\/products\/spi-cdi26103b-spi-dial-drop-indicator-0-25-0","provider":"Voomi Supply","version":"1.0","type":"link"}
