Traceability of Mitutoyo Standards
Mitutoyo ensures and maintains traceability of various types of precision measuring instruments by holding standards of length and other physical quantities that are directly traceable to the national standards for use in calibrating the working standards used for the calibration of measuring instrument products supplied to industry. Furthermore, Mitutoyo offers a temperature calibration service which is indispensable for high-accuracy length measurement. The Mitutoyo traceability system with the optical frequency comb at the top level, ensuring performance equivalent to that of the Japan’s national standard, and the calibration technology supporting this system are the basis of highly accurate and reliable products offered to customers.
