## Long description

INSIZE 3220-30 is a mechanical outside micrometer designed for accurate linear measurement of external dimensions in workshop and quality-control environments. The instrument measures shaft diameters, thicknesses and other external features with a thimble scale, fine spindle adjustment and ratchet stop to help ensure repeatable contact pressure. Built for routine use in metalworking and inspection, this micrometer provides a straightforward mechanical solution where digital readout is not required.
Advantages
The mechanical design offers reliable, maintenance-friendly operation without batteries. A thimble scale combined with a fine spindle enables precise graduations for consistent readings, while the ratchet stop limits operator-applied force for repeatability. The frame and measuring faces are arranged for stable contact with workpieces, and the simple construction makes the micrometer compatible with standard workshop practices for calibration and care.
Suitable for
 Measuring external diameters of shafts and pins
 Checking thickness of flat parts and sheet metal
 Quality-control inspection in production and maintenance
 General metalworking and mechanical engineering tasks
Key specifications
 Measuring type: mechanical outside micrometer for external dimensions
 Measuring range: 25–50 mm (typical for this model class)
 Resolution: conventional thimble graduations suitable for 0.01 mm reading
 Spindle: fine spindle with ratchet stop for controlled contact force
 Scale: engraved thimble scale for manual reading
 Application environment: workshop, inspection bench, production control
How to use
Place the micrometer anvils around the external feature to be measured and rotate the thimble until the spindle contacts the workpiece. Use the ratchet stop to apply consistent contact pressure and avoid over-tightening. Read the value from the sleeve and thimble graduations, applying any necessary zero adjustments or calibration offsets according to workshop practice. After use, clean the measuring faces and store the micrometer in its protective case to preserve accuracy.
Usage recommendations
For accurate results, verify zero before measuring and perform periodic calibration against gauge blocks. Keep measuring faces clean and free from debris; avoid measuring directly on burrs or unfinished surfaces. Use the ratchet stop to ensure repeatable measurements and allow the micrometer to reach thermal equilibrium with the measured part for precision work.
