A pinhole detector or holiday detector checks coatings by means of electrical voltage. Microscopically small defects (> 20um) can then be detected in the coating of a surface. Even minimal defects in surface coatings can have fatal consequences so careful testing with the right pinhole detector is vital.

Pinhole Detection Product


PoroTest 7

Helps you locate pores, fissures and other faults in non-conductive coatings on conductive basis material such as steel, aluminium, concrete, etc. It 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
