For precise work, it’s essential to measure accurately. Digital calipers are the perfect tool for this, providing clear and easy-to-read results. The top scale is for the inner diameter, while the bottom scale measures the outer and wire diameters. With just the touch of a button, you can convert measurements from millimeters to inches. These calipers can measure objects up to 4 inches or 100mm in size, and the large display is easy to read. Additionally, the automatic shut-off feature helps to conserve battery life.
