Vernier Caliper

A Vernier caliper is a precision measuring instrument used to measure dimensions with high accuracy, especially in mechanics and engineering. It consists of a main scale and a sliding Vernier scale, allowing users to take precise measurements of lengths, diameters, and depths. The main scale is graduated in millimeters or inches, while the Vernier scale provides additional resolution, allowing measurements to be taken to a fraction of the smallest division on the main scale. This dual-scale design enhances the precision of measurements, making Vernier calipers valuable tools in various scientific and technical applications.
