Handy, reliable LED lamps are essential for non-destructive materials testing.

For magnetic particle testing UV-A LED lamps supply with the necessary background illumination during inspection.

For magnetic particle testingas well as penetrant testing - in the case of applying fluorecent test products - UV-A LED lamps enable precise inspection. Indications become contrasty visible under UV-A radiation.

White light LED lamps are mainly used for visual testing.

For specific applications blue light LED lamps are particularly suitable. However, general recognition e.g. by respective application standards is still pending.
