Digital calipers are precision measuring tools used to determine the dimensions of an object. They can measure internal and external dimensions, as well as depths, with high accuracy. The digital display shows measurements in either millimeters or inches, making it easy to read and interpret. These tools are commonly used in various fields, including engineering, woodworking, and metalworking. Digital calipers often feature a stainless steel construction for durability and may include additional functions like zeroing and data hold. They are a valuable tool for anyone needing precise measurements in their work.
