Each micrometer in the set features a 0.001 mm digital resolution and an accuracy rating of 0.003 mm, making this set well-suited for precision dimensional inspection work in machining, manufacturing, and metrology applications. The carbide-tipped measuring faces resist wear over repeated use, and the friction thimble provides consistent measuring force to reduce operator-to-operator variation. The IP54 ingress protection rating means the instruments are protected against dust ingress and splashing water, supporting use in typical shop floor environments. Each unit is factory calibrated and ships with a short-form certificate of calibration.\u003c\/p\u003e\n\u003cp\u003eThis micrometer set is intended for machinists, quality control technicians, tool and die makers, and precision measurement professionals who need outside diameter and thickness measurement capability across the full 0 to 4 inch range without swapping instruments. The set is suited for both production floor inspection and toolroom use. Battery-powered digital readout eliminates manual interpolation of vernier graduations, reducing read error on critical dimensions. The included case organizes all four micrometers for storage and transport between workstations or job sites.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-piece set covering 0 to 4 inches (0 to 100 mm) total measurement range\u003c\/li\u003e\n  \u003cli\u003e0.001 mm digital resolution for precise dimensional readings\u003c\/li\u003e\n  \u003cli\u003e0.003 mm accuracy with factory calibration and included short-form certificate of calibration\u003c\/li\u003e\n  \u003cli\u003eCarbide-tipped measuring faces for extended wear resistance\u003c\/li\u003e\n  \u003cli\u003eFriction thimble ensures consistent, repeatable measuring force\u003c\/li\u003e\n  \u003cli\u003eIP54 rated for dust and splash resistance in shop floor environments\u003c\/li\u003e\n  \u003cli\u003eLR44 batteries included; rotating spindle design for standard outside measurement technique\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standalone 4-piece electronic outside micrometer set for general precision measurement applications requiring 0 to 4 inch outside diameter and thickness capability.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eOutside micrometers are calibrated instruments and should be handled and stored according to standard metrology practices. Before use, verify the zero setting of each micrometer against the included standard and adjust as needed. Avoid dropping or impacting the measuring faces, as this can affect calibration. Store the instruments in the provided case when not in use to protect the measuring faces and electronic components.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range (Inch)\u003c\/strong\u003e: 0 to 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range (mm)\u003c\/strong\u003e: 0 to 100 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 0.001 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.003 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Friction\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Face Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIngress Protection Rating\u003c\/strong\u003e: IP54\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBattery Size\u003c\/strong\u003e: LR44 (included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCalibrated\u003c\/strong\u003e: Yes, with short-form certificate of calibration\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 19.69 inches (L) x 11.86 inches (W) x 1.86 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 5.1 pounds\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: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CMS160622004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51691249598770,"sku":"CMS160622004","price":1024.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/556ccea237ea1f050e7f7d714558c976.jpg?v=1788282189","url":"https:\/\/voomisupply.com\/products\/spi-cms160622004-electronic-outside-micrometer-set-4-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
