Rißprüfung zerstörungsfreie Werkstoffprüfung / Rissprüfung

Single frequency test systems ...
detect the expected defect reliably.
BUT the unknown defects remain undectected, because a single frequency does not "see" the whole picture.

ibg's multi-frequency test systems ...
... detect all defects with their broad frequency range, even the unexpected ones.

Each alloy, each material ...
... has its individual permeability curve, unique like a fingerprint.
