metrology
Science of quantification
Metrology is the science of measurement—establishing standards, developing techniques, and ensuring accuracy and precision.
It encompasses everything from calibrating laboratory instruments to maintaining international measurement standards.
The company's metrology department ensures all gauges meet specification.
Not to be confused with meteorology, the study of weather.
