Dial Gauges

A dial indicator, also known as a dial gauge or dial test indicator, is a precision measuring instrument used to measure small linear distances or deviations with high accuracy. Dial gauges are widely used in manufacturing, machining, and quality control for tasks such as:

• Measuring part dimensions and tolerances
• Checking surface flatness, parallelism, and runout
• Aligning and setting up machinery and equipment
• Inspecting geometric features like roundness or concentricity

Contact point type

A contact point, also known as a probe or stylus, is a critical component of a dial indicator or digital indicator used for precise measurement. It is the part that physically contacts and interacts with the surface being measured. The point serves as the interface between the indicator and the workpiece, transferring any linear movement or deviation to the indicator's internal mechanisms for amplification and display on the dial or digital readout. Contact points are often replaceable and interchangeable on dial and digital indicators, allowing users to swap them as needed for different applications.
