Metrology & Calibration Standards

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.

Metrology advances

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

Shared expertise

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