Precision
Precision relates to the consistency of repeated measurements. A measurement system is considered precise if it produces similar results under consistent conditions, irrespective of whether those results are accurate. Precision does not imply accuracy.

Repeatability
Repeatability is the ability of an instrument to return to the same measurement when used repeatedly under the same conditions, without changing the setup or operators. It is a measure of the instrument’s consistency over short periods and under stable conditions.

Reproducibility
Reproducibility is the degree to which measurements are consistent when repeated under different conditions, such as with different instruments, operators, and locations. It emphasizes the instrument’s reliability across varied conditions.
