The dial indicator stand is a precision measuring tool used to support and position a dial indicator for accurate measurements. The stand typically consists of a heavy granite base with a flat surface, a vertical column that can be adjusted in height, and an arm or holder that supports the dial indicator. 

The granite base provides a stable and rigid foundation that helps minimize vibrations and maintain accuracy. The flat surface of the base can be used as a reference for measuring flatness, parallelism, and other surface features of the workpiece.
