          Air Gauge Micrometer OD Probes



         In some conditions, where a "touching method" is demanded, a direct type of air limit gauge is not a proper choice. The measurement should use
         indirect contact type, as air nozzle hole is set under a leaf with carbide ball on its measuring point. The carbide ball directly contact the product
