ElectroPhysik Pin hole

A pinhole detector checks coatings by means of electrical voltage. Microscopically small defects (>20µm) 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. Urgent action is required when just the smallest defect is found during pinhole detection of surface coatings. Minimal defects in the coating are sufficient to cause major damage. The PoroTest 7 pinhole detector from ElektroPhysik is an indispensable aid in the search for pores, cracks and other defects in non-conductive coatings on conductive base materials
