The indicator reads in both inch and metric units on an integrated LCD display, switching between modes without tools. Accuracy is 0.0002 inches (0.004 mm) with a resolution of 0.01 mm, making it suitable for close-tolerance setups. Two CR2032 3V lithium batteries are included. Machinists, tool and die makers, and metrology technicians install and use this instrument in shop and inspection environments.\u003c\/p\u003e\u003cp\u003eThe 49506 is applied wherever a standard drop-style indicator is needed for measuring runout, flatness, parallelism, or part-to-part variation. The 8 mm stem diameter fits standard indicator holders, magnetic bases, and transfer stands common to machining and inspection setups. It is appropriate for use in both production and job-shop environments where digital readout is preferred over a dial face for faster, unambiguous readings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-inch (50 mm) measurement range with 0.0002-inch accuracy\u003c\/li\u003e\n\u003cli\u003eDual-unit readout: inch and metric on LCD display\u003c\/li\u003e\n\u003cli\u003e8 mm stem diameter fits standard indicator holders and magnetic bases\u003c\/li\u003e\n\u003cli\u003eResolution of 0.01 mm for fine measurement tasks\u003c\/li\u003e\n\u003cli\u003eIncludes two CR2032 3V lithium batteries — ready to use out of the box\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style drop indicator compatible with standard 8 mm stem indicator holders, magnetic bases, and surface gauge arms used in general machining and inspection applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMounting is performed by clamping the 8 mm stem into an indicator holder or magnetic base arm. Ensure the clamp screw is snug but not overtightened to avoid damaging the stem. When using the indicator on powered machine tools, confirm the spindle is stopped and the machine is in a safe state before zeroing or repositioning. Handle the contact point and stem carefully — drop indicators are precision instruments and can lose calibration if struck or dropped.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Range (Inch)\u003c\/strong\u003e: 2.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Range (mm)\u003c\/strong\u003e: 50.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy (Decimal Inch)\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy (mm)\u003c\/strong\u003e: 0.004 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResolution (mm)\u003c\/strong\u003e: 0.01 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnits of Measure\u003c\/strong\u003e: Inch and Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay Type\u003c\/strong\u003e: LCD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Diameter\u003c\/strong\u003e: 8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBatteries Included\u003c\/strong\u003e: 2x CR2032 3V Lithium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 10 inches L x 5.5 inches W x 3.25 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 49506\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541767586098,"sku":"49506","price":860.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6ac1d2cc4b03c193641ed025948fe503.jpg?v=1785884456","url":"https:\/\/voomisupply.com\/products\/starrett-49506-electronic-drop-indicator-2-inch-range","provider":"Voomi Supply","version":"1.0","type":"link"}
