NOVOTEST ED-3D Pinhole Detector was designed for rapid non-destructive testing of the continuity of coating (e.g. porosity of film) with thickness up to 500mkm according to ASTM G62-A.
Pinhole Detector is designed for testing the porosity of partially painted places and other discontinuities of protective dielectric coatings on metal products by putting low voltage through a sponge which is soaked in a liquid electrolyte with high penetrating properties.
