For traceability, KYOWA has systematically established a standard calibration route from national standards to field-use working instruments with in-company standards in between. The in-company electrical standards are periodically inspected by Japan Electric Meters Inspection Corporation and Japan Quality Assurance Organization and the in-company mechanical standards, by Nippon Kaiji Kyokai and National Institute of Advanced Industrial Science and Technology so as to maintain the system for product quality assurance.

KYOWA is registered as an accredited calibration laboratory in the “General Field of Calibration: Force, Electricity ( Direct Current & Low Frequency) and Time & Frequency” field of the traceability system of Measurement Law.
