## Summary description

INSIZE micrometer 3220-100 is an internal-contact measuring instrument for internal diameter measurement in the 75–100 mm range. Type C configuration provides precise contact surfaces for repeatable readings. Suitable for workshops and quality control where accurate internal dimension checks are required. Compact design for machining, inspection and assembly tasks.

## Long description

INSIZE micrometer 3220-100 is an internal-contact measuring instrument designed for precise measurement of internal diameters from 75 to 100 mm. The Type C configuration features accurately finished contact surfaces and a compact frame suited to machining, inspection and assembly tasks. This tool is intended for use in workshops and quality control environments where repeatable, reliable internal dimension checks are required.
Advantages
The micrometer’s Type C contact geometry ensures consistent seating and minimal measurement variation when measuring bore diameters. A compact, rigid body reduces deflection and improves stability during measurement. The instrument is engineered to provide a clear, repeatable measuring action that supports frequent use in industrial and laboratory settings.
Suitable for
Measuring internal diameters of cylindrical bores between 75 mm and 100 mm
Quality control inspections in production lines and inspection labs
Workshops and maintenance shops performing component verification
Assembly tasks requiring verification of internal fits and clearances
Key specifications
Measuring range: 75–100 mm
Contact type: internal-contact, Type C geometry
Design: compact frame for confined spaces and stable handling
Application: precision internal diameter measurement for machining and inspection
How to use
Before measurement, ensure the instrument and the workpiece are clean and at similar ambient temperature to minimise thermal error. Insert the measuring contacts into the bore and expand the anvils until both contact surfaces engage the internal surface gently but firmly. Use the thimble or ratchet stop, if fitted, to apply consistent measuring force. Read the measurement according to the micrometer’s scale or transfer the value to the connected readout system if applicable. Take multiple measurements at different orientations if high accuracy or roundness assessment is required.
Usage recommendations
Store the micrometer in a protective case when not in use, avoid exposing it to strong shocks or corrosive environments, and perform regular calibration checks to maintain measurement accuracy.
