Accurate crack detection by Griffon

Practical benefits

Sharp white background contrast: The white developer layer highlights defects as bright red lines so you spot hairline cracks immediately.
Versatile non-porous surface use: You reliably inspect metals and non-porous plastics for welding flaws, grinding defects, and fatigue cracks.
Safe chloride-free formula: Thanks to the chloride-free formulation, you carry out non-destructive testing without risking corrosion on sensitive surfaces.

In a nutshell

The right choise for

With the 300 ml Griffon Devmor developer spray, you can instantly detect microscopic surface defects that are invisible to the naked eye. This white developer spray serves as the crucial step in non-destructive penetrant testing alongside Griffon Primor and Griffon Verimor. Once applied, the white contrast layer draws the penetrant dye out of surface flaws, exposing hairline cracks, welding defects, and porosity as sharp red lines. Its chloride-free formulation ensures safe inspection on metals and non-porous plastics without damaging the material. Ideal for dependable maintenance inspections and rigorous quality control on welded joints and pipework.
