Pulse Porosity Detector

PULSE POROSITY DETECTOR1-170x170


The compact DC Porosity (Holiday) Detectors are used to ensure the longevity of coating systems by locating pin-holes, air-bubbles and porosity in non-conductive coating on conductive substrate, including concrete.

APPLICATION

Used for detection of coating porosity (pin-holes, or holidays) in dielectric (insulation type) coatings on conductive substrates, including concrete.

Regulated ‘Pulsed’ output fully adjustable.

Ideal for Use :

  • In moist conditions
  • On wet coating surfaces
  • On contaminated coating surfaces
  • On carbon-impregnated coatings, ie: carbonated rubber
  • On plastic or fiberglass type coatings likely to become electrostatically charged
  • Coating Thickness Range : 150 to 25,000μm using P40 model

In compliance with the requirements of :
