PCWI Pulsed Porosity Detector


Coating flaws such as pinholes, bubbles, or porosity, cause coating failure as moisture or contaminants infiltrate through the coating flaws down to the substrate. The PCWI PULSED HIGH VOLTAGE POROSITY DETECTOR is a light-weight, portable unit for detection of porosity or coating flaws in dielectric coatings on conductive substrates.

PCWI Pulse Porosity Detectors are designed for use in moist conditions, on wet or contaminated coating surfaces, on carbon-impregnated coatings such as carbonated rubber, and on plastic or fibreglass-type coatings likely to become electrostatically charged, PCWI Pulse Porosity Detectors come in three models: P 20 (2 – 20kV), P40 (5 – 40kV) for all carbonize coatings, and the PCWI P50, designed specifically for use with Rubber Coatings.

PCWI’s Pulsed Holiday Detector provides regulated pulsed output which is fully adjustable across the full range of the meter, providing accurate, precise voltage output for all coating thicknesses where high-voltage testing is appropriate. Alternative names for high voltage porosity detectors include ‘spark testers’ or ‘jeepers’.

PCWI PULSED HOLIDAY DETECTOR Features:

  • lightweight (2.2 kg)
  • LCD display of voltage
  • visual and audible alarms when fault is found:
    • alarm range: P20: 2 - 20kV P40: 5 - 40kV P50: 10 - 50kV
  • battery condition indicator
  • voltage ranges from 0 to 20 Kv (P20), 0 to 40 kV (P40), 0 - 50 kV (P50 - rubber coatings only) fully adjustable
  • fully-adjustable voltage by 100 v increments
  • constant test current
  • finger-tip controls
  • clip-on battery pack
  • overcharge protection
  • earphones for noisy environments
  • ABS case
  • full range of flat brushes, internal and external pipe brushes, pipeline coils, and rubber brushes.
