It delivers a measurement range of 0 to 12.70 mm with a resolution of 0.001 mm and an accuracy of 0.003 mm, making it suitable for surface deviation checks, runout measurements, and fine comparative gauging. The contact point is made from carbide, providing wear resistance during repeated contact cycles. Machinists, tool-and-die makers, metrology technicians, and quality inspectors typically work with this instrument on manual and CNC setups alike.\u003c\/p\u003e\n\u003cp\u003eThis indicator fits applications where electronic readout is preferred over analog dial interpretation. It is used in precision metrology labs, machine shop floor inspection stations, and fixture-based measurement setups. The 20 mm dial diameter keeps the instrument compact for use in tight or obstructed workpiece areas. It is suited to both horizontal and vertical mounting configurations on magnetic bases, indicator holders, and surface plate setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.001 mm resolution for fine incremental measurement\u003c\/li\u003e\n  \u003cli\u003e0.003 mm accuracy over the full measurement range\u003c\/li\u003e\n  \u003cli\u003eCarbide contact point resists wear during high-cycle inspection tasks\u003c\/li\u003e\n  \u003cli\u003eMeasurement range of 0 to 12.70 mm covers typical surface deviation checks\u003c\/li\u003e\n  \u003cli\u003e20 mm dial diameter supports compact placement in restricted workspaces\u003c\/li\u003e\n  \u003cli\u003eElectronic output eliminates analog dial parallax reading errors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style electronic test indicator for use with standard indicator mounting stems and holders common to precision metrology and machine shop inspection setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a machinist or metrology technician using a standard indicator holder, magnetic base, or dedicated fixture arm. Ensure the contact point is positioned at the correct stylus angle relative to the workpiece surface to avoid cosine error in readings. Do not overtighten the clamping stem, as this can affect spindle movement and measurement accuracy. Zero the indicator after mounting and before taking any reference measurements.\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 12.70 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 0.001 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.003 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Length\u003c\/strong\u003e: 7.3 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCalibrated\u003c\/strong\u003e: No\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: 543-302-10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51558135005490,"sku":"543-302-10","price":593.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f6df9362b96bb5e33c4c3e9e12cf6a0b.jpg?v=1786404399","url":"https:\/\/voomisupply.com\/products\/mitutoyo-543-302-10-electronic-test-indicator-12-7mm","provider":"Voomi Supply","version":"1.0","type":"link"}
