Specialized category for precision measuring instruments dedicated to precision measurement and quality control in manufacturing sites. Handles high-precision equipment used for inspection and measurement of product dimensional accuracy, geometric tolerances, and surface quality, centered on dimensional and shape measuring instruments such as calipers, micrometers, dial gauges, height gauges, coordinate measuring machines (CMM), vision measuring systems, surface roughness testers, roundness measuring machines, and contour measuring instruments. Includes measuring instruments with calibration certificates compliant with JIS and ISO standards, as well as in-line measuring devices for in-process inspection, providing essential measurement solutions for establishing and maintaining quality assurance systems. Distinguished from material testing machines and component analysis equipment, this instrument group specializes primarily in physical measurement of dimensions, shapes, and positions.
