ACO Co., Ltd.

ACO Co., Ltd. was established as a sound measuring instrument manufacturer in 1972, and amassed an extensive performance record through its accumulation of research and development in cooperation with user companies and research institutes at universities. Based on these achievements, ACO branched out into the vibration-measuring segment in 1977 and continues to expand today as one of Japan's largest enterprises in the sensor industry. We began development of an export market in 1976. Since that time, we have established business relationships in the U.S., the U.K., Germany, Korea, Taiwan and other countries around the world, where "ACO-made sensors" are highly regarded.
