Tubular Inside Micrometer Archives

Wide range of inside diameter measurements possible by combining one or more interchangeable rods.
Each interchangeable rod is marked with its measuring range.
For models supplied with more than one interchangeable rod, the full measuring range is achieved by combining spacing collars with the rods.
Both micrometer head and rods are satinchrome finished throughout.
The sleeve is rotated to adjust the index line position when setting to a length standard.
Setting ring (nominal size below 300mm), CERA Inside Micro Checker, and Gauge Block accessory set are provided as a reference gage for datum adjustment (refer to page C-47, C-26, and E-17 – E20 for details).
