摘要
An apparatus for scanning header tube holes includes a probe assembly designed to engage the surface of the header encircling a header tube hole. The probe assembly includes a spring mounted sensor, in a preferred arrangement, an eddy current probe. A mechanism is provided for supporting and positioning the probe assembly. The mechanism is adapted, in operation, with resilient rings engaging the tube stub. A drive device is provided for imparting axial and circumferential movement to the probe relative to the surface of the hole which is to be inspected.
