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)
