Using the principles of Air-gauging we design and manufacture Air Gauges to measure Dimensions - such as Inside and Outside Diameters with fine tolerances. We are capable of producing gauges for measuring Major and Minor Diameters of Splines with such technology also. These gauges are interfaced with Electronic Instruments of Computers to display the results in Analog or Digital format. Each Gauge is supplied with Min. and Max. Masters for calibrating the Instrument.
