What is calibration and why is it important? Calibration is the technical comparison of a measuring instrument against a suitable reference standard to determine its measurement performance. Learn the difference between calibration and adjustment, understand error, correction, uncertainty and traceability, and discover why regular calibration is essential for reliable measurements in industrial and laboratory applications.
Calibration is the process of comparing a measuring instrument with a known reference standard to check its accuracy. It helps identify error, apply correction where required, maintain reliable measurements, support audits, and build confidence in quality decisions.
Traceability in calibration ensures that every measurement result is linked to recognized national or international standards through a documented, unbroken chain of calibrations with known uncertainty. It is the foundation of reliable, comparable, and audit-ready measurements.
