Description

The INSIZE 3221-300 Tubular Inside Micrometer is a precision tool designed to measure internal dimensions ranging from 50 to 300 mm. Its tubular construction provides excellent rigidity while remaining lightweight, ensuring ease of use and reliability for extended measurement tasks. The micrometer features a fine graduation of 0.01 mm, delivering accurate and repeatable results suitable for industrial and mechanical applications. Equipped with a 13 mm micrometer head travel, this tool offers flexibility in various measurement scenarios. The accuracy of the micrometer is calculated as (6 + L/50) µm, where L represents the maximum measuring length in millimeters. Optional accessories, including setting rings (code 6312) and gauge block accessories (code 6881), can further enhance its functionality and performance.
