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.

校正に影響を与える6つの要素 
校正サービスのサプライヤの選定は、非常に簡単なことだと思われています。なぜなら、校正という作業自体には大きな差はなく、認定サプライヤ(ISO9000登録やISO17025認定など)であればどのサービスやサプライヤを選択しても類似したサービスが提供されるはずだからです。ところが、実際にはそうではありません。校正には規制がないため、校正の成果物と価値には大きなばらつきがあるのです。
