Replacement of Traceability system charts

Mitutoyo Corporation (Mitutoyo Japan) has introduced an optical frequency comb, with performance equivalent to that of the Japan's National Standard, as a top-level length standard and for which we have obtained accreditation by the Japan Calibration Service System (JCSS).

We are now preparing for the transition of our traceability system to include this new standard, therefore traceability charts issued from 1st September 2017 includes the optical frequency comb.

If you wish to request the traceability system charts as of the time calibration is performed, or request a copy of the calibration certificate for the actual standards used in the calibration, please inform us (when you request the calibration). We will issue the traceability system charts with the standards used in the calibration.

Thank you very much for your understanding.
