How to Choose the Correct Measuring Tool for Any Application

There are many options to choose from when deciding on a dimensional measurement tool. Consider these application-based factors when selecting a measurement solution.

Bring the Surface Finish Check to the Part

Dedicated handheld gages can assist the operator in making critical checks.

Reading What the Dial Indicator Is Saying

Dial indicators provide good value for their resolution. With a glance, one can quickly determine if the part is larger or smaller than the master setting and by a degree of how much.
