Application Areas

· For general defect evaluation (surface inspection of aircraft components such as blades, hubs, landing gears, etc.)

· For rivet holes or bolt holes, cracks on the inner surface of the holes can be detected without removing or detaching fasteners.

· Detection of Surface Cracks on Various Metal Parts and Welds

· Detection of in-service copper, titanium, aluminum, zirconium and other non-ferromagnetic heat exchanger tubes

· Detection of interlayer gap corrosion of composite materials, such as detection of multilayer structures of aircraft, aluminum skin and fuselage wing joints, etc.

· Monitoring the change of heat treatment state and sorting materials

· With additional functions of weld seam detection with anticorrosive coating, crack depth measurement and conductivity measurement (optional), the instrument is especially suitable for in-service and pre-service detection in the fields of aviation, aerospace, electric power, petrochemical and mechanical manufacturing, etc.
