It delivers a resolution as fine as 0.00002 inches and an accuracy of 0.0001 inches over a full 1-inch (25.40 mm) range. The LCD display provides clear, direct digital readout in both inch and metric units. Equipped with a data output port, it supports integration into measurement networking and statistical process control (SPC) systems. A licensed metrologist, machinist, or quality control technician typically operates this instrument during inspection and gauging work.\u003c\/p\u003e\n\u003cp\u003eThe 543-722B is suited for surface, height, and runout measurements on machine tools, surface plates, and inspection fixtures in both production and toolroom settings. Its flat back and straight connection type make it compatible with standard indicator holders and magnetic base setups. The indicator operates on a CR2032 battery, which is included. Measurements can be taken in inches or millimeters, making it versatile across shops that work in either unit system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLCD digital display with selectable inch and metric readout\u003c\/li\u003e\n  \u003cli\u003eResolution selectable at 0.00002, 0.00005, 0.0001, or 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003eAccuracy of 0.0001 inches over a 1-inch measurement range\u003c\/li\u003e\n  \u003cli\u003eIntegrated analog bar graphic for rapid deviation monitoring\u003c\/li\u003e\n  \u003cli\u003eTolerance judgment function with user-set upper and lower limits\u003c\/li\u003e\n  \u003cli\u003eData output port for SPC system and measurement network integration\u003c\/li\u003e\n  \u003cli\u003eCarbide contact point for extended wear resistance\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 dovetail and post-type indicator holders and magnetic base systems commonly used in metrology and machine tool inspection setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMount the indicator using a standard indicator holder that accepts the straight connection type on a flat-back body. Ensure the contact point is perpendicular to the measurement surface to avoid cosine error. Do not overtighten the clamping mechanism on the indicator stem, as excessive force can affect accuracy. Replace the CR2032 battery when the low-battery indicator appears on the LCD.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 0.00002 \/ 0.00005 \/ 0.0001 \/ 0.0005 inches (selectable)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 0.00 inches (0.00 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\u003eMeasuring Force\u003c\/strong\u003e: 1.5 N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisplay Type\u003c\/strong\u003e: LCD with analog bar\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: Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Source\u003c\/strong\u003e: Battery (CR2032 included)\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\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\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: 543-722B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51564149899570,"sku":"543-722B","price":732.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb3f3f233f8e39d5ece283d7773ab9ff.jpg?v=1786512427","url":"https:\/\/voomisupply.com\/products\/mitutoyo-543-722b-electronic-drop-indicator-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
