Compact Pulse Holiday Detectors

Porosity Detection in Coatings 

Conforms to ASTM G62-87 (1998), NACE RP0274-98, NACE RP0490-2001, NACE RP0188-99, ASTM D4787-93 (1999), JIS G-3491, JIS G-3492, ANSI/AWWA C214-89, ANSI/AWWA C213-94, ISO 2746:1998 & AS3894.1-2002

 

Applications :

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

 

Regulated pulsed output is fully adjustable, ideal for use:

  • In moist conditions
  • On wet coating surfaces
  • Very thick coatings
  • On contaminated coating surfaces
  • On carbon-impregnated coatings, i.e. carbonated rubber
  • On plastic/fiberglass type coatings likely to become electrostatically charged
  • Coating thickness range: 6 to 1000 mils (150 to 25,000µm) with the P40 holiday detector (and even thicker coatings with the P60)
 

P20 : 1-20kV

P40 : 5-40kV

 

Industrial Kit :
