Pulse Holiday Detectors

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

The PCWI Compact Pulse Porosity Detector is fully adjustable,
has regulated pulsed output up to 20kV, 40kV or 50kV. All
pulse models can be used for porosity and holiday testing
of carbon impregnated coatings such as carbonated rubber,
thick coatings such as rubber linings and on ‘plastic’/fibreglass
type coatings likely to become electrostatically charged.
Features
 
Light weight ABS case
LED digital display of applied voltage
The P20 and the P40 holiday detectors are available in industrial and pipeline kits. The P60 is available only in an industrial kit.
Voltage ranges of 500 to 20kV or 40kV and 10kV to 50kV, fully adjustable
Clip-on battery pack
Constant test current
Wet or dry condition sensitivity control on P20 and P40 porosity detectors
Overcharge protection
Single power supply
Low battery condition indicator
Earphones for noisy environments
 
The Pulse 50kV model is the only portable battery operated model on the market capable of generating voltages from 10,000 to 50,000 volts. The P50 was designed for use with Rubber Coatings. It is not for use on Pipelines.
Applications
Used for detection of coating porosity (pinholes 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
- 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)
