What are Plunger Dial Gauges?

Plunger Dial Gauges are more commonly known as Dial Indicators.  Dial Indicators are the most flawless tools to indicate the run-out i.e., the misalignment between the axis of the workpiece and the axis of the rotation of a spindle. The aim of the dial is to reduce the deviation. 

Dial Indicators are also used in various other applications like comparative measurements, checking parallelism with gauges and fixtures etc. 

Plunger Dial Gauges are available both in analog and digital models and can be used based on their applications.
