It uses an extension rod system to span a measurement range of 8.0000 to 60.0000 inches, making it well suited for large-bore applications where a standard inside micrometer falls short. The instrument resolves to 0.0001 inch (0.001 mm) and includes a digital counter with data output capability, allowing readings to be logged directly to a compatible data collection system. Licensed metrology technicians, quality control inspectors, and precision machinists are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis inside micrometer is applied in manufacturing, machining, and quality assurance environments where large internal diameters must be verified to four decimal places. The extension rod configuration allows a single instrument to cover a wide span without switching to a completely different gage. Typical applications include measuring cylinder bores, large pipe fittings, housing bores, and industrial machinery components. The data output feature supports SPC workflows and digital record-keeping in production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasurement range: 8.0000 to 60.0000 inches via extension rod system\u003c\/li\u003e\n  \u003cli\u003eResolution of 0.0001 inch and 0.001 mm for high-precision readings\u003c\/li\u003e\n  \u003cli\u003eDigital counter display for fast, direct reading without interpolation\u003c\/li\u003e\n  \u003cli\u003eData output port supports connection to SPC systems and data loggers\u003c\/li\u003e\n  \u003cli\u003eExtension rod type design covers a wide internal diameter range with one instrument\u003c\/li\u003e\n  \u003cli\u003eGage depth of 1 inch for consistent contact in bore measurement setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style electronic inside micrometer intended for use with compatible MITUTOYO extension rod sets and accessories appropriate to the 337-series instrument family, as specified in MITUTOYO documentation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInside micrometers of this type are handled and calibrated by metrology technicians or qualified machinists. Before use, verify the instrument is zeroed against a known reference standard appropriate to the measurement range. Extension rods must be fully seated and locked before taking a measurement to prevent false readings. This instrument is not rated for use in environments with excessive vibration, coolant immersion, or temperature extremes outside the manufacturer-specified range.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 8.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 60.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResolution (Decimal Inch)\u003c\/strong\u003e: 0.0001 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResolution (mm)\u003c\/strong\u003e: 0.001 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRod Type\u003c\/strong\u003e: Extension\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Depth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDigital Counter\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eData Output\u003c\/strong\u003e: Yes\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: 6.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111601\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: 337-304\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51557397365042,"sku":"337-304","price":1687.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d0c1d030de11df13512d4a05991c6a8.jpg?v=1786387232","url":"https:\/\/voomisupply.com\/products\/mitutoyo-337-304-electronic-inside-micrometer-8-60-in","provider":"Voomi Supply","version":"1.0","type":"link"}
