Metrology and Calibration

Feel confident that Keysight metrology is behind every measurement you make.

Measurement Confidence

Know that every measurement is traceable to National Metrology Institutes (NMIs) through Keysight-engineered calibration procedures that verify instrument specifications.

Advanced Metrology

Rely on Keysight engineers who work with the NMIs to develop rigorous measurement techniques in engineering metrology and emerging technologies.

Engineering metrology assists with metrology and measurement

Metrology Expertise

Stay up-to-date on changing compliance requirements and their practical applications by working with Keysight metrologists who collaborate with international standards organizations.
