Vernier caliper

A vernier caliper is a precision measuring tool used to take accurate measurements of small objects. It consists of a main scale and a sliding vernier scale, which allows for precise readings up to one-tenth of a millimeter. The caliper can be used to measure the inner and outer dimensions of an object, as well as the depth of a hole or groove. It is commonly used in engineering, machining, and woodworking to ensure precise and accurate measurements for the production of components and parts. The vernier caliper is an essential tool for anyone working in fields that require precise measurements and is widely used in workshops, laboratories, and manufacturing facilities.
