## Long description

INSIZE calibration gauge ring set WZORZEC LUKOW 1–7 mm (model 4801-17) is a precision reference set of gauge rings that covers internal diameters from 1 mm to 7 mm. The set is intended for calibration and verification of small bores, bore gauges and internal measuring instruments in metrology labs and workshop quality-control environments. Manufactured to provide stable reference dimensions, these rings support repeatable checks and adjustment of measuring tools that require high accuracy at sub-millimetre scale.
Advantages
The calibration rings offer stable, wear-resistant contact surfaces and tight dimensional tolerances suitable for verification tasks on fine bore gauges. Their compact diameter range from 1 to 7 mm makes the set practical for small-part inspection and for instruments used in precision machining and assembly. The set helps ensure measurement traceability and consistent instrument performance without introducing unnecessary complexity.
Suitable for
Calibration and verification of bore gauges and internal micrometers
Quality control of small bores in precision components
Inspection tasks in metrology laboratories and workshops
Setting reference standards for inspection fixtures and gauges
Key specifications
Diameter range: 1 mm to 7 mm in graduated increments
Material: hardened and wear-resistant engineering steel (typical for calibration rings)
Finish: precision-ground internal bore for accurate contact
Tolerance: manufactured to tight dimensional tolerances appropriate for calibration use
Set includes multiple ring sizes covering the specified range for stepwise calibration
How to use
Select the gauge ring that corresponds to the nominal diameter you need to verify. Clean the ring and the instrument contact surfaces to remove debris and oil. Insert the measuring instrument or bore gauge into the ring, ensure proper seating and alignment, then take readings according to the instrument procedure. Use rings across the range to check instrument linearity and to adjust zero or calibration offsets where applicable. Record results for traceability and repeat checks periodically to monitor instrument stability.
Usage recommendations
Store the rings in a clean, dry case to prevent corrosion and protect the ground surfaces. Use gloves or finger cots during handling to avoid transferring oils and contaminants. For critical calibration tasks, perform measurements in a temperature-controlled environment and follow laboratory calibration procedures to maintain traceability.
