It delivers an accuracy of +\/-0.00020 inches, making it suitable for close-tolerance work in machining, fabrication, and mechanical service environments. The measuring faces are carbide-tipped for durability and wear resistance during repeated use. A ratchet thimble provides consistent measuring pressure, and a lever-style lock nut holds the reading once set. The unit carries an IP65 rating, meaning it is protected against dust ingress and low-pressure water spray, which suits use on the shop floor or in field service conditions.\u003c\/p\u003e\u003cp\u003eThis micrometer is used wherever outside diameter, thickness, or linear dimension measurements in the 4 to 5 inch range are required. Typical applications include machine shops, tool rooms, quality control inspection, and mechanical maintenance. Trades that commonly use this instrument include machinists, toolmakers, pipefitters, and mechanical service technicians working with precision components. The digital readout eliminates interpolation error, making it a practical choice for both production environments and single-point inspection tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDigital outside micrometer with 4 to 5 inch measurement range\u003c\/li\u003e\n\u003cli\u003eAccuracy of +\/-0.00020 inches per ASME B89.1.13\u003c\/li\u003e\n\u003cli\u003eCarbide-tipped measuring faces resist wear for extended service life\u003c\/li\u003e\n\u003cli\u003eIP65 rating provides protection against dust and water spray\u003c\/li\u003e\n\u003cli\u003eRatchet thimble ensures repeatable, consistent measuring force\u003c\/li\u003e\n\u003cli\u003eLever lock nut secures spindle position for hands-free reading transfer\u003c\/li\u003e\n\u003cli\u003eIncludes CR2032 lithium battery — ready to use out of the box\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose digital outside micrometer for any application requiring measurement in the 4 to 5 inch range. No specific instrument replacement compatibility is stated by the manufacturer for this part number.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis instrument requires no installation, but calibration verification should be performed before first use and at regular intervals per your quality system requirements. Store the micrometer in its case away from direct heat sources and strong magnetic fields. Battery replacement uses a standard CR2032 lithium cell — power down the unit before opening the battery compartment. Handle the measuring faces carefully to avoid nicking the carbide tips, which will affect accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMicrometer Type\u003c\/strong\u003e: Digital Outside\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: +\/-0.00020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasuring Face Material\u003c\/strong\u003e: Carbide-Tipped\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLock Nut Type\u003c\/strong\u003e: Lever\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP Rating\u003c\/strong\u003e: IP65\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B89.1.13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery\u003c\/strong\u003e: CR2032 Lithium (1 included)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotating Spindle\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCalibrated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 7 inches L x 3.4 inches W x 0.97 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CMS220519005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51714953937202,"sku":"CMS220519005","price":357.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/259c4952c5cf823010ab6c5ac93c7e2e_68182a60-d174-4acd-83bf-4f4cac9258cf.jpg?v=1788508299","url":"https:\/\/voomisupply.com\/products\/spi-cms220519005-electronic-outside-micrometer-4-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
