Many industries confuse Calibration and Verification, but they serve different purposes in measurement control.

Calibration is the process of comparing an instrument with a traceable standard to find its measurement error and ensure accuracy. It provides detailed results and measurement uncertainty.

Verification is checking whether the instrument meets required tolerance limits and gives a simple PASS or FAIL decision.

In simple words:
Calibration tells how accurate the instrument is, while Verification tells whether it is acceptable to use.

Both are important — calibration ensures traceability and accuracy, and verification confirms usability in production.
