Vernier Caliper

A Vernier caliper is a precision measuring tool used to determine the dimensions of objects with high accuracy. It consists of a main scale and a sliding component called the Vernier scale, which allows for precise readings of length, width, or thickness. The caliper has jaws that can open and close to grasp objects, and some models include depth gauges and internal measurement jaws. It is commonly used in engineering, manufacturing, and science to ensure components meet exact specifications. The device provides measurement readings typically to the nearest 0.02 mm or 0.001 inches, making it essential for quality control and detailed measurements.
