Dial Test Indicator (DTI)

A Dial Test Indicator (DTI) is a high-precision tool used to measure small variations in the surface or alignment of a workpiece. Commonly used in machining, quality control, and inspection, the DTI provides accurate readings of runout, flatness, and alignment by measuring minute deflections with its highly sensitive dial face. The needle on the dial moves in response to surface irregularities, making it easy to detect even the smallest deviations in components. Ideal for professionals in industries such as automotive, aerospace, and manufacturing, the DTI ensures precision and reliability in critical measurement tasks, helping to maintain tight tolerances and high-quality standards.
