To ensure thorough safeguarding against corrosion, the protective layers must be free of pores, cracks and embedded foreign bodies. This prevents aggressive substances from coming into contact with the carrier material. With Fischer’s holiday detectors, you can easily identify cracks in coatings made of electrically non-conductive materials. We offer the model: POROSCOPE® HV20. They offer a range of test voltages suitable for almost every coating thickness and every kind of coating material.

The pore testing is carried out by means of a constant DC voltage between 4 and 20 kV. But you’re at no risk of danger: Fischer high-voltage pore testers meet all the safety requirements of ISO 2746. In addition, these handheld devices are very robust – ideal for conducting inspections even under harsh conditions. Regardless of how challenging the application, you’re always properly equipped with Fischer holiday detectors.  From fine pore inspections on plastic coatings or sterile, air-tight packaging for medicinal or food products right through to checking the plastic or enamel coatings used to protect tanks, ships' hulls or piping against corrosion.
