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 25,000┬Ám) with the P40 holiday detector (and even thicker coatings with the P60)
 

P20 : 1-20kV

P40 : 5-40kV

 

Industrial Kit : 

Holiday Detector (P20, P40 & P60) with clip-on power pack, 10-hour charger, spare battery pack (P50 model only), probe handle with 79" (2m) long cable, 2.4" (60mm) connector for flat brush electrodes, 22 (7m) long ground cable with clamp, fan brush, 10" (250mm) wide flat brass wire brush, 18" (450mm) long probe extension, air-operated earphones, shoulder and waist harness, carrying case , operation instructions with conformance certificate.
