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 makes it easy to read measurements, often in millimeters or inches, and many models feature a zeroing function for added convenience. These tools are commonly used in various fields, including engineering, woodworking, and metalworking. Digital calipers are typically made of stainless steel for durability and may include features like a locking screw to hold measurements in place. They are essential for anyone needing precise measurements in their work.
