Air Ring Gauges

Air ring gauges are precision instruments used for measuring the external diameters of cylindrical objects. They work by using air pressure to measure the gap between the gauge and the part, providing a non-contact method for accurate measurements. Air gauges are often used for checking dimensions like size, taper, and ovality. The image shows a set of KCP air ring gauges, which are known for their precision and quality. These gauges are commonly used in industries such as automotive, metalworking, and aerospace.
