The worlds largest metrology company was founded in 1934 by Yehan Numata with one product, the micrometer. Mitutoyos original vision was to make the best mechanical micrometers in the world and to produce them in quantities that made them affordable. This vision was expanded in the next several decades to include a wider product offering focused on mechanical, dimensional gaging products. Mitutoyo focused its research and development, and production efforts on creating the most advanced micrometers, calipers, indicators and other measurement tools in the world. As electronic technology became more widespread in the 70s, Mitutoyo began to manufacturer digital, measuring tools. As statistical process control (SPC) was introduced, Mitutoyo led the world in the development of output gages, interfaces, data collectors and analysis software to take advantage of this new metrology science. When the computer made its way into the field of metrology, Mitutoyo again shifted its focus to include this technology into its product offering, and began to push measuring accuracies into the sub-micron range. Today, Mitutoyo presents its 6000 plus products as integrated, computer-based metrology systems that can be interconnected to form closed-loop-measuring networks. Mitutoyo America Corporation was formed in 1963 and is headquartered in Aurora, Illinois (just outside of Chicago). As the leading metrology company in the world, Mitutoyo is committed to future product development that applies breakthrough technologies to its full range of dimensional measurement tools, instruments and systems.
