It measures from 0 to 1.0000 inches (0 to 25.40 mm) with an accuracy of plus or minus 0.0012 inches, making it suitable for dimensional inspection tasks that require reliable, repeatable readings. The indicator uses a straight connection type and applies a measuring force between 0 and 1.8 N to the contact point. Machinists, toolmakers, and quality technicians typically install and operate this instrument on surface plates, indicator stands, or transfer fixtures in machine shops and inspection labs.\u003c\/p\u003e\n\u003cp\u003eThis drop indicator suits applications in precision dimensional inspection on the shop floor or in a controlled metrology environment. It is appropriate for checking flatness, runout, concentricity, and part-to-part variation where electronic readout improves speed and documentation compared to a traditional dial indicator. The straight connection type accommodates standard indicator holder stems commonly found on magnetic bases and comparator stands used in general manufacturing and inspection workflows.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasurement range of 0 to 1.0000 inches (0 to 25.40 mm) for versatile dimensional checks\u003c\/li\u003e\n  \u003cli\u003eAccuracy of plus or minus 0.0012 inches for reliable inspection results\u003c\/li\u003e\n  \u003cli\u003eElectronic readout eliminates analog dial interpretation errors\u003c\/li\u003e\n  \u003cli\u003eMeasuring force of 0 to 1.8 N minimizes deflection on delicate workpieces\u003c\/li\u003e\n  \u003cli\u003eStraight connection type fits standard indicator holders and magnetic base stems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style electronic drop indicator compatible with standard straight-stem indicator holders, magnetic bases, and comparator stands used in precision metrology and dimensional inspection setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and setup should be performed by a qualified machinist, toolmaker, or metrology technician familiar with indicator mounting practices. Secure the indicator stem firmly in the holder to eliminate stem slip before zeroing the instrument. Ensure the contact point travels perpendicular to the measured surface to avoid cosine error. Handle the spindle and contact point carefully to avoid shock loading, which can affect calibration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 0.0000 inches (0 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 1.0000 inches (25.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: plus or minus 0.0012 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Force\u003c\/strong\u003e: 0 to 1.8 N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCalibrated\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: MITUTOYO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 543-852A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51558401966386,"sku":"543-852A","price":888.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3814bc9fa9f89eb4dbb37bd580a4dd47.jpg?v=1786411336","url":"https:\/\/voomisupply.com\/products\/mitutoyo-543-852a-electronic-drop-indicator-1-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
