Metrology Calibration Center was established by combining the laser calibration department, which had been recognized as meeting Japan's national standards, and the calibration department for standard scales and temperature, which had been recognized as having Japan's finest measurement capabilities. On November 1, 2005, Metrology Calibration Center was accredited in three calibration categories: lasers, standard scales and temperature. The Center provides calibration services as a global MRA accredited laboratory, at the top of Mitutoyo's length traceability system.
