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.

ACO's products are based on human living environments. We manufacture a diverse line up of products for quality management, maintenance, controls, product research and development, various kinds of instruments, construction and medical departments.
