It delivers a resolution of 0.00005 inches and an accuracy of 0.00015 inches, making it suitable for high-tolerance work in machining, engine rebuilding, and precision assembly. The contact surfaces carry a titanium nitride finish for extended wear resistance. A ratchet stop thimble provides consistent measuring force, and the large LCD display with 7.5 mm character height allows clear readings under shop conditions. An IP65 ingress protection rating shields the instrument from dust and coolant splash. Installed and operated by machinists, toolmakers, and precision measurement technicians.\u003c\/p\u003e\n\u003cp\u003eThe 468-271 is used in environments where accurate internal diameter measurement is critical, including machine shops, manufacturing floors, and engine rebuild facilities. Its 3-contact-point design self-centers in the bore, reducing operator error and improving repeatability. The unit includes data output capability, allowing measurements to be logged directly to a PC or statistical process control system. It ships with a plastic protective case and a single SR44 battery installed, ready for immediate use out of the box.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasurement range: 2.5 to 3.0 inches with 0.00005-inch resolution\u003c\/li\u003e\n  \u003cli\u003eAccuracy rated at 0.00015 inches for high-tolerance applications\u003c\/li\u003e\n  \u003cli\u003eIP65-rated housing resists dust and coolant ingress\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride finish on contact surfaces for long-term durability\u003c\/li\u003e\n  \u003cli\u003e3-point contact design self-centers for consistent bore readings\u003c\/li\u003e\n  \u003cli\u003eData output port supports SPC and PC-based measurement logging\u003c\/li\u003e\n  \u003cli\u003eTUV certified; large 7.5 mm LCD characters for easy shop-floor readability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use as a precision bore measurement instrument in applications requiring internal diameter measurement between 2.5 and 3.0 inches. Compatible with standard SPC data collection systems via the built-in data output port.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInsert the 3-contact head into the bore and apply consistent pressure using the ratchet stop to ensure repeatable measuring force. Calibrate against a known ring gauge before use and re-zero as needed per standard metrology practice. Keep the instrument clean and dry when not in use; despite the IP65 rating, avoid prolonged submersion or direct high-pressure fluid exposure. Battery replacement uses a standard SR44 cell.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 0.00005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.00015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet Stop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Contact Points\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Titanium Nitride\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIngress Protection Rating\u003c\/strong\u003e: IP65\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisplay\u003c\/strong\u003e: LCD, 7.5 mm character height\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eData Output\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBattery\u003c\/strong\u003e: SR44 (1 included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.86 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Plastic case\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertification\u003c\/strong\u003e: TUV Certified\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: 468-271\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51558918062386,"sku":"468-271","price":1792.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fac25d3d4554c00b5c16565f26ccbf3b.jpg?v=1786422868","url":"https:\/\/voomisupply.com\/products\/mitutoyo-468-271-electronic-inside-micrometer-2-5-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
