Sensitivity to surface defects.

Able to detect defects of 0.5mm in length under favourable conditions.

Able to detect defects of 0.5mm in length under favourable conditions.Can detect through several layers.

The ability to detect defects in multi-layer structures (up to about 14 layers), without interference from the planar interfaces.

The ability to detect defects in multi-layer structures (up to about 14 layers), without interference from the planar interfaces.Can detect through surface coatings. Able to detect defects through non-conductive surface coatings in excess of 5mm thickness.

The ability to detect defects in multi-layer structures (up to about 14 layers), without interference from the planar interfaces.Can detect through surface coatings. Able to detect defects through non-conductive surface coatings in excess of 5mm thickness.Accurate conductivity measurements. Dedicated conductivity measurement instruments operate using eddy currents.

Relatively uniform parts can be inspected quickly and reliably using automated or semi-automated equipment, e.g. wheels, boiler tubes and aero-engine disks.

Relatively uniform parts can be inspected quickly and reliably using automated or semi-automated equipment, e.g. wheels, boiler tubes and aero-engine disks.Little pre-cleaning required.

Only major soils and loose or uneven surface coatings need to be removed, reducing preparation time.

Only major soils and loose or uneven surface coatings need to be removed, reducing preparation time.Portability.

Portable test equipment is very small and light, some of the latest equipment being as small as a video cassette box and weighing less than 2kg.
