It covers a measurement range of 20mm to 40mm (approximately 0.79 inches to 1.58 inches) and delivers a resolution of 0.005mm (0.0002 inch), making it well-suited for close-tolerance inspection work. The gage uses a ball-type contact point configuration, which allows it to seat accurately inside grooves and bores. It is intended for use by machinists, quality control technicians, and precision measurement professionals working in production or inspection environments.\u003c\/p\u003e\n\u003cp\u003eThis gage is applied where internal groove diameters must be verified quickly and accurately. Typical use cases include inspecting snap ring grooves, retaining ring seats, and similar internal features on machined components. The minimum groove depth accommodation is 7mm, making it practical for shallow internal features. It is well suited for bench inspection, in-process checks on the shop floor, and receiving inspection of machined parts across light manufacturing and precision machining operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInternal measurement range: 20mm to 40mm (0.79 inches to 1.58 inches)\u003c\/li\u003e\n  \u003cli\u003eResolution: 0.005mm (0.0002 inch) for fine tolerance readout\u003c\/li\u003e\n  \u003cli\u003eBall-type contact points for accurate seating in grooves and bores\u003c\/li\u003e\n  \u003cli\u003eMinimum groove width of 0.0600 inches for narrow internal feature access\u003c\/li\u003e\n  \u003cli\u003eMinimum groove depth: 7mm for shallow feature compatibility\u003c\/li\u003e\n  \u003cli\u003eDigital electronic display for fast, direct reading without interpolation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style internal electronic caliper gage for precision measurement applications requiring digital readout of internal groove and bore diameters in the 20mm to 40mm range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis gage is a handheld precision instrument and does not require mechanical installation. Before use, zero the gage per the manufacturer calibration procedure and verify contact points are clean and undamaged. Store the gage in its protective case when not in use to prevent contact point wear and electronic damage. Battery replacement and routine calibration should be performed according to the manufacturer service schedule.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 20mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 40mm (1.58 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 0.005mm (0.0002 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Depth\u003c\/strong\u003e: 7mm minimum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 0.0600 inches minimum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Type\u003c\/strong\u003e: Ball\/Ball\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 9.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 pounds\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: 209-937\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51563793449266,"sku":"209-937","price":953.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4ddcd959ddacb291b62da4fcbe67ee64.jpg?v=1786503685","url":"https:\/\/voomisupply.com\/products\/mitutoyo-209-937-internal-electronic-caliper-gage","provider":"Voomi Supply","version":"1.0","type":"link"}
