PINHOLE DETECTOR
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
