Pencil surface probes are equipped with an adjustable collar that helps to achieve the optimal angle for inspection and ensures greater stability. Belonging to the family of detachable stainless-steel shaft surface probes, these pencil probes feature small coils and a small-diameter housing built for higher frequencies. They are usually used for surface breaking crack detection.

Advantages
Excellent for small defect detection.
Good stability on flat surfaces.
Available with Powerlink™ technology.
Broad selection of frequency-ranges.
Wide variety of coil configurations available.

Applications
Through paint inspection of aircraft rivets.
Aircraft structure, unit, and engine inspection.
Through paint detection of stress corrosion cracking in stainless and carbon steel.
Surface crack inspection of manufacturing and transportation equipment.
