POROSCOPE® offers 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 0.8 and 40 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.

Available in three voltage ranges:

  • POROSCOPE® HV5: 0.8–5kV
  • POROSCOPE® HV20: 4–20kV
  • POROSCOPE® HV40: 8–40kV
