Application
Reliable porosity detection device for detection pores and holes in insulating materials on conductive substrates such as steel, aluminium, for example
· coatings on oil, gas or water pipelines
· linings of tubes, vessels or storage tanks
· protective coatings on hulls, oil tanks, vessels, pipelines including fittings
· enamel, epoxy and plastics coatings
Flaws in protective coatings such as pores, cracks and fissures, if undetected, may impair the corrosion resistance of a product. The PoroTest 7 by ElektroPhysik has been specifically designed for non-destructive porosity testing of such coatings, based on automatic test voltage control specific to the thickness of material to be tested and vice versa. The major fields of application of the PoroTest 7 range from vendor inspection to quality assurance in corrosion protection.
PoroTest 7 offers a great variety of electrodes. Test voltages:
· 0,5.. 7 kV for testing materials from 0,03 mm ... 1,7 mm thickness with electrode P7
· 3... 30 kV for testing materials from 0,5 ... 9 mm thickness with electrode P30
· 6... 35 kV for testing materials from 1,4 mm ... 11,3 mm thickness with electrode P35
