Inside diameter dial indicator, high-precision inside diameter gauge

Description

Product Introduction:

Internal diameter dial indicators are suitable for industries such as machining, automotive manufacturing, and precision instrumentation. They are used to perform high‑precision measurements of workpiece internal diameters and can assess critical dimensions including hole roundness, cylindricity, and fit clearances.

Product Features:

① Suitable for comparative measurement of the inner diameter of workpieces.

② This series of dial indicators is equipped with an excellent guiding bridge, ensuring self-centering accuracy and reliability.

③ One end of the measuring head is a movable probe, while the other end is an interchangeable probe that can be swapped out depending on the diameter of the hole being measured.

④ Users have multiple options for the configured indicator display, as needed.
