DeFelsko PosiTest LPD Low Voltage Pinhole Detector


DeFelsko is pleased to announce their new PosiTest LPD Low Voltage Pinhole Detector.

Low voltage or wet sponge porosity testing is used to locate discontinuities in coating systems, including pinholes, cracks, bubbles, or thin spots in cured coatings of up to 20 mils thick (500 µm). Porosity testing of thicker coatings is performed with a high-voltage tester, commonly referred to as holiday detector, porosity detector, spark tester, and sometimes a jeep tester. (please click to check out our high voltage holiday detectors)

Flaws in coating systems permit the intrusion of moisture or potentially corrosive substances that can degrade the substrate and cause early coatings failure. Detection of pinholes, cracks, bubbles, or weak spots enables the coatings contractor to take action to repair the coating before costly degradation or failures occur.

The PosiTest LPD Low Voltage Pinhole Detector can be used to detect holidays in coatings applied to any conductive substrate, including steel and concrete. Light-weight and easy to use, the new PosiTest LPD is available in a basic kit with the standard rectangular sponge, or a complete kit that also includes the hardware for a variety of test applications, including flat surfaces, internal pipes or tubes, and a roller brush option.

PosiTest LPD Complete Kit includes everything contained in the Basic Kit plus:

Adaptable Sponge Hardware:

  • Rectangle
  • Roller
  • Internal diameter
  • 8 x 8" (20 x 20 cm) sponge sheet to cut custom sponge sizes
  • Wetting agent

Extension Accessories:

  • Extension rods provide additional 0.6 m (2') of reach
  • Universal adapters to extend existing paint rollers and poles
  • 12 m (40') ground wire
  • 4.5 m (15') hot wire
  • magnetic grounding post

 

 

PosiTest LPD Accessory Pack can be purchased
separately to convert the Basic Kit to a Complete Kit.

 

 

 

 

 

 

 

Optional Accessories also include:

  • PosiTest LPD base rod for an additional 0.3m (1') length - purchased individually; multiple extension rods can be connected to extend reach
     
  • 8 x 8 " (20 x 20 cm) sponge sheets to cut additional or custom sponge sizes / shapes
     
  • Wetting Agent - 60 ml bottle *

*Why use wetting agent? Pinholes can be tiny enough to impair the passage of water to the substrate; a particular problems with thicker coatings. Using a surfactant or wetting agent reduces the surface tension of the water, improving the penetrability of the solution through the pinhole.
