Certificate of National Institute of Technology and Evaluation

Kyowa's Standard Instruments Office is registered as an accredited calibration laboratory in the Force/Electricity (Direct Current & Low Frequency) field.

JCSS (Japan Calibration Service System) was established to assure traceability of measurement according to provisions of Measurement Law. National Institute of Technology and Evaluation examines at the International Accreditation Center (IAJapan) whether or not an applicant calibration laboratory has the technical capabilities and traceability of measurement in conformity with the international standard ISO/IEC 17025 (JIS Q 17025) for calibration.
