Johnson & Allen have launched the L4 liquid penetrant series which includes NEON-L4 and EMU-L4. Together this pair function as a sensitivity level 4 inspection system which is the highest detection classification of any type of penetrant.

Aerospace grade penetrant - Suitable for highly critical components

NEON-L4 is a post-emulsifiable fluorescent penetrant for type D applications which was formulated to contain minimal harmful substances while having an ultra-high sensitivity. This makes NEON-L4 suitable for aerospace applications and for the inspection of highly critical components.

EMU-L4 is a penetrant emulsifier and remover which is applied after the dwell period so excess penetrant can be removed.

NEON-L4 and EMU-L4 are intended to work together and should not be used with any other kind of consumable product.
