Air gauges are high-precision, non-contact measuring instruments used for accurate inspection of internal diameters, roundness, taper, and surface finish. They operate on the principle of air flow or air pressure, providing extremely fine resolution and repeatable results without damaging the component. Ideal for high-volume and precision-critical applications, air gauges are widely used in automotive, aerospace, and engineering industries for fast, reliable, and consistent quality control. All types of air gauges can be supplied in various configurations to meet specific customer measuring requirements.
