Quality Policy

Nagano Keiki delivers world-class quality.

We were the first Japan Calibration Service System-accredited calibration laboratory for pressure measurement in Japan

In 1998, the Ueda Measurement Instrument Plant was registered as the first JCSS-accredited laboratory in Japan for the pressure classification (Accreditation #0080). Nagano Keiki has established a calibration system based on Japanese national standards and is entrusted with JCSS calibration for three types of pressure gauges, namely dead-weight testers, digital pressure gauges, and mechanical pressure gauges. We perform the highest level of calibration accuracy in the nation. Also, we have acquired ILAC-MRA accreditation providing international recognition of our calibration reports.

世界基準The company is accredited under JCSS, which uses ISO/IEC 17025 (JIS Q17025) as its accreditation criteria, which is based on the accreditation scheme ISO/IEC 17011. The accreditation body (IA Japan) that operates JCSS is a signatory of the mutual recognition agreement with the Asia Pacific Accreditation Cooperation (APAC) and the International Laboratory Accreditation Conference (ILAC).
