In addition to world-class research and manufacturing facilities, Mitutoyo has also built a global service network that is anchored by comprehensive ISO/IEC 17025 accredited calibration services. The rigors of accreditation have created global recognition and trust in measurement. Accreditation is the best tool to ensure measurement traceability and provides for transparency in the capabilities of measurement services.
