The Metrology Equipment segment offers an extensive array of measuring instruments. This includes multipurpose devices like coordinate measuring machines, instruments for analyzing surface texture, contour, roundness, and cylindrical profiles, as well as optical and optical shaft measuring systems, and X-ray CT systems. Furthermore, the company develops automatic measurement solutions such as in-process and post-process gauge products, various sensors, electric and air micrometers, high-precision digital measurement instruments, and laser interferometers. The company adopted its current name, Tokyo Seimitsu Co., Ltd., in April 1962, having previously operated as Tokyo Seimitsu Kogu Co., Ltd.
