Digital bore gauges are precision measuring tools used to determine the internal diameter of cylindrical objects, such as pipes or engine cylinders. They provide accurate readings by using electronic sensors, which display measurements on a digital screen. This makes it easier for users to read and interpret results compared to traditional mechanical gauges. These gauges often come with features like data storage and the ability to connect to computers for further analysis. They are commonly used in industries such as manufacturing and automotive, where precise measurements are crucial for quality control and ensuring proper fit of components.
