The measuring range spans 1 to 2 inches with a graduation of 0.001 inch and a resolution of 0.00005 inch, delivering an accuracy of 0.0002 inch. A ratchet stop thimble controls measuring force for consistent, repeatable readings. The satin chrome finish reduces glare and resists corrosion in shop environments. This tool is suited for metrology technicians, machinists, and quality control personnel working with thin parts such as saw blades, disc springs, and sheet stock.\u003c\/p\u003e\n\u003cp\u003eThe 123-126 is used in precision measurement applications where standard micrometer anvils cannot properly seat on a thin or disc-shaped part. The 20 mm disc anvil with a 0.70 mm edge thickness allows contact on narrow surfaces that would otherwise be inaccessible. The rotating spindle and data output capability make this unit compatible with SPC data collection systems. It is applicable in manufacturing, tool and die, and quality assurance settings where tight tolerances must be verified on disc-profile components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasuring range: 1 to 2 inches with 0.001 inch graduation and 0.0002 inch accuracy\u003c\/li\u003e\n  \u003cli\u003e20 mm disc anvil with 0.70 mm edge thickness for contact on thin and narrow workpieces\u003c\/li\u003e\n  \u003cli\u003eRatchet stop thimble ensures consistent measuring force and repeatable results\u003c\/li\u003e\n  \u003cli\u003eRotating spindle with data output port for SPC or digital readout integration\u003c\/li\u003e\n  \u003cli\u003eIP65-rated water and dust resistance for use in wet or coolant-present environments\u003c\/li\u003e\n  \u003cli\u003eSatin chrome finish on steel anvil and spindle for corrosion resistance and reduced glare\u003c\/li\u003e\n  \u003cli\u003eIncludes plastic carrying case and one SR44 battery\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a precision measurement instrument for outside measurement of disc-profile and thin-edged workpieces in the 1 to 2 inch range.

Before use, verify the micrometer is zeroed at the 1 inch reference point using the appropriate standard. Handle with clean, dry hands or cotton gloves to prevent corrosion from skin oils on precision surfaces. Store in the included plastic case when not in use to protect the disc anvil and spindle from damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 0.001 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 0.00005 inch \/ 0.001 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0002 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Mechanical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet Stop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Edge Thickness\u003c\/strong\u003e: 0.70 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle\u003c\/strong\u003e: Rotating, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnvil Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Satin Chrome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eData Output\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWater Resistance Rating\u003c\/strong\u003e: IP65\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBattery\u003c\/strong\u003e: 1 x SR44 (included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Plastic Case\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: 123-126\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51564126110002,"sku":"123-126","price":366.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/09b101d188a6f14aa841672a706c80f5.jpg?v=1786511619","url":"https:\/\/voomisupply.com\/products\/mitutoyo-123-126-mechanical-disc-micrometer-1-to-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
