A vernier caliper is a precision measuring instrument used to measure internal dimensions, external dimensions, and depths with high accuracy. It consists of a main scale and a sliding vernier scale, along with measuring jaws and a depth rod. Vernier calipers are commonly used in engineering, machining, metalwork, and mechanical workshops for accurate measurement of objects and components.
Operation:
The vernier caliper operates by sliding the movable jaw along the main scale until the object is firmly held between the jaws or measured by the depth rod. The measurement is taken by reading the value on the main scale and adding the corresponding reading from the vernier scale for precise results. It can measure thickness, diameter, depth, and inside dimensions accurately, making it useful for detailed mechanical and technical work.
