PoroTest 7: Greater safety for coated surfaces

The PoroTest 7 helps you to locate pores, fissures and other faults in non-conductive coatings on conductive basis material such as steel, aluminium, concrete, etc. It therefore provides optimal protection from:

  • Internal and external corrosion
  • Secondary damage due to minute coating defects
  • Damage to highly sensitive foodstuffs
  • Dangerous chemical reactions
  • Cost-intensive re-coatings due to undetected defects

The PoroTest 7 is designed for use with boilers, pumps, tanks and other receptacles, but also for offshore installations, drilling rigs, ships or pipelines.
