High Voltage Pulse Holiday Detector
3 Models: P20, P40 & P60
Measuring Ranges:
Model P20: 1,000 to 20,000 Volts
Model P40: 5,000 to 40,000 Volts
Model P60: 10,000 to 60,000 Volts
Resolution: 100 Volts
The PCWI Compact Pulse Porosity Detector is fully adjustable,
has regulated 'pulsed' output up to 20kV, 40kV or 60kV. 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.
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
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 60kV, 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
- Earphones for noisy environments
- Low battery condition indicator
- The Pulse 60kV model is the only portable battery operated
model on the market capable of generating voltages from 10,000
to 60,000 volts
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)
