About ADC

Message from President

ADC Corporation was founded as Takeda System Corporation in 1971. Since then, we have developed analog measurement technologies that we cultivated in Takeda Riken Industries (current Advantest Corporation), and have contributed to society in testing and measurement fields as a measuring instrument company.
We separated form Advantest Corporation in 2003, and started business specialized in digital multimeters, DC voltage/current source monitors, digital electrometers, optical measuring instruments and measuring instrument systems. Additionally, we launched the first modular and multifunction instrument in 2019.
Our mission is to pursue the essence of generic measuring instruments by developing innovative measurement technologies using our accumulated analog technologies so as to contribute to the society. In keeping with the mission, we will be growing with our customers as a trusted company.

Hiroshi Mochida
Representative Director and President
