The instrument delivers an accuracy of 0.005 mm over a 5 mm measurement range, with a graduation of 0.01 mm. Measuring faces are machined from solid carbide to resist wear during repeated use. A satin chrome finish reduces glare under shop lighting. This micrometer requires a setting standard to establish the reference point before measurement, which is standard practice for caliper jaw instruments of this type.\u003c\/p\u003e\n\u003cp\u003eCaliper jaw micrometers are used when bore micrometers or telescoping gauges cannot access narrow grooves, undercuts, or small internal features. The 145-185 is suited for toolroom inspection, machinist use on production floors, and quality-control checks where inside dimensions must be confirmed to within a few microns. It is intended for use by machinists, metrologists, and precision tooling technicians working in manufacturing, maintenance, and inspection environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5 mm measurement range for small inside-diameter and groove measurement\u003c\/li\u003e\n  \u003cli\u003e0.005 mm accuracy for high-precision toolroom and inspection work\u003c\/li\u003e\n  \u003cli\u003e0.01 mm graduation for direct reading without interpolation\u003c\/li\u003e\n  \u003cli\u003eSolid carbide measuring faces for extended wear life\u003c\/li\u003e\n  \u003cli\u003eSatin chrome finish reduces reflection and corrosion\u003c\/li\u003e\n  \u003cli\u003eMechanical analog design with no battery or digital counter required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification caliper jaw micrometer suitable for use with standard Mitutoyo setting standards required to zero the instrument prior to measurement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA calibrated setting standard must be used to set the micrometer to the reference point before taking measurements — do not attempt to use this instrument without zeroing it first. Handle measuring faces with care; solid carbide is hard but brittle and can chip if dropped. Clean faces with a lint-free cloth before and after use. Store in the provided case away from magnetic fields, vibration, and temperature extremes to maintain calibration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.005 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 0.01 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Face Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Satin Chrome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDigital Counter\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSetting Standard Required\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 145-185\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51563997954354,"sku":"145-185","price":332.14,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b6ada1bc4b687230b7632d08635d152.jpg?v=1786508725","url":"https:\/\/voomisupply.com\/products\/mitutoyo-145-185-caliper-jaw-micrometer-5mm-range","provider":"Voomi Supply","version":"1.0","type":"link"}
