It covers a measurement range of 0 to 1 inch with an accuracy of 0.0004 inches and a resolution of 0.0005 inches. The unit features an LCD display for easy reading and an aluminum housing for durability in shop environments. Machinists, tool-and-die technicians, and quality control inspectors use this indicator when verifying flatness, runout, and surface alignment on workholding setups and fixtures.\u003c\/p\u003e\n\u003cp\u003eThis drop indicator is suited for use on surface plates, magnetic bases, and indicator stands in both production and inspection settings. The center lug back mounting style is standard for drop indicator holders and magnetic arm assemblies. Measurements are displayed in both inch and metric units, making it versatile for shops working to either standard. A CR2032 battery is included, so the unit is ready to use out of the box.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasurement range of 0 to 1 inch (0 to 25.00 mm)\u003c\/li\u003e\n  \u003cli\u003eAccuracy of 0.0004 inches (0.010 mm)\u003c\/li\u003e\n  \u003cli\u003eResolution of 0.0005 inches (0.010 mm)\u003c\/li\u003e\n  \u003cli\u003eLCD display for clear numeric readout\u003c\/li\u003e\n  \u003cli\u003eCenter lug back for standard drop indicator mounting\u003c\/li\u003e\n  \u003cli\u003eAluminum housing for lightweight durability\u003c\/li\u003e\n  \u003cli\u003eDual-unit readout: inch and metric\u003c\/li\u003e\n  \u003cli\u003eBattery-powered with CR2032 included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard drop indicator holders, magnetic bases, and indicator arms that accept a center lug back mounting style and a 3\/8-inch stem diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or metrology technicians. Secure the center lug back to a compatible indicator holder or magnetic arm before applying any contact pressure to the spindle. Ensure the stem is clamped on the 3\/8-inch diameter section and that the indicator is oriented plumb to the surface being measured. Replace the CR2032 battery when the low-battery indicator appears on the LCD to maintain measurement accuracy.\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 1 inch (0 to 25.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0004 inches (0.010 mm \/ 10 micrometers)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 0.0005 inches (0.010 mm \/ 10 micrometers)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisplay Type\u003c\/strong\u003e: LCD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Inch and Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack Type\u003c\/strong\u003e: Center Lug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Source\u003c\/strong\u003e: Battery (CR2032, included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: FOWLER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 54-530-145-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FOWLER","offers":[{"title":"Default Title","offer_id":67918703853874,"sku":"54-530-145-0","price":1071.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f93612bb3a0a9db789f5489ec27ef857_7f1ca8c7-b72e-4489-bfb6-615441b6877b.jpg?v=1791272433","url":"https:\/\/voomisupply.com\/products\/fowler-54-530-145-0-electronic-drop-indicator-0-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
