A precision measuring instrument, characterized by a small contact point connected to a needle on a graduated dial, serves to indicate dimensional variations. This tool effectively detects deviations from a specific surface or plane. For example, it can accurately measure the runout of a rotating shaft or the flatness of a machined surface by displaying the magnitude of the variation on its dial.
The significance of this instrument lies in its ability to provide highly accurate measurements, essential for quality control, precision manufacturing, and machinery maintenance. Its use contributes to ensuring components meet specified tolerances, which in turn improves overall product performance and longevity. Historically, this measuring device has been a mainstay in workshops and inspection departments due to its reliable and easily interpretable readings.
