Calibrated micrometer for outside diameter measurement Measures 0 to 1 inch (0 to 25 mm) with 0.00005 inch (0.001 mm) resolution and ±0.00005 inch accuracy, designed for taking outside diameter measurements in harsh workshop conditions LCD screen displays in inches and metric units, enabling quick unit reading and conversion Plastic components are oilresistant and measuring faces are carbidetipped for durability in tough environments Ratchet stop helps provide uniform pressure for precise, repeatable measurements Benefits and key attributes precision in demanding shops: the 0.00005 inch resolution and ±0.00005 inch accuracy deliver reliable OD readings even when conditions are dirty or oily Easy to read and switch units: the LCD displays in both inches and metric units, reducing error from manual conversions Durable construction for harsh environments: oilresistant plastics protect the instrument, and carbidetipped measuring faces resist wear over time Consistent measurements: the ratchet stop maintains uniform contact pressure, supporting repeatable results across multiple measurements Practical use scenarios Metalworking and turning operations: verify the outside diameter of a turned shaft or rod to ensure it meets tolerance during setup and inspection Aviation, automotive, or maintenance settings: check OD of cylindrical components such as pins, sleeves, or tubing that may be exposed to oil or coolant Fabrication and quality control: confirm OD of sleeves or bushings during assembly to ensure proper fit before installation
