High-voltage holiday detection on thick coatings.

Compact DC (Holiday) Porosity Detector - PCWI
SKU pcwi-DETECTOR-POROSIDAD-COMPACT-DC
Used to extend coating-system service life by locating pinholes, air bubbles and porosity (holidays) in non-conductive coatings on conductive substrates, including concrete; PCWI also rents DC detectors to customers within Australia. Suited to pipeline, tank and structure coating operations, and ideal for storage tanks, valves and piping. Housed in a fully portable ABS case, the detector delivers a stabilized DC output of up to 30 kV, with a constant-current source that maintains the applied test voltage.

PCWI Compact Pulse Detectors
SKU pcwi-DETECTORES-PULSO-COMPACTOS
The P20 and P40 models are used for porosity and holiday testing of carbon-impregnated coatings such as carbon-filled rubber, thick coatings such as rubber linings, and plastic/fiberglass-type coatings that can carry an electrostatic charge. These models are ideal for wet conditions and on damp or contaminated coating surfaces, and are commonly known as holiday detectors, spark testers, porosity testers or jeep testers. They detect coating porosity (pinholes, or holidays) in dielectric (insulating) coatings on conductive substrates, including concrete, with a fully adjustable regulated pulsed output.

Crest meters (1)
Brushes and coil electrodes (4)
Brush and coil electrodes for pipeline and flat-surface holiday detectors.

PCWI Pipeline Coil
SKU pcwi-BOBINAS-HOLIDAY-DETECTOR
Pipeline coil electrodes wrap around pipe sections of a specific nominal diameter so a holiday detector can test the full external coating circumference.

PCWI External Pipe Brush
SKU pcwi-CEPILLO-RODAMIENTO-EXTERNO
The external pipe brush rolls around the outer circumference of coated pipe to detect pinholes and discontinuities without disassembly of the line.

PCWI Internal Brush (Spiral / Track)
SKU pcwi-CEPILLOS-DISCO-INTERNO-HOLIDAY
Internal brushes mount on a probe to test the interior coating of a pipe section for holidays and porosity as the brush is drawn through the bore.

PCWI Flat Brush
SKU pcwi-CEPILLOS-PLANOS-HOLIDAY
Flat brush electrodes attach to high-voltage holiday detectors to scan large, flat coated surfaces for pinholes and porosity.
Surface profile (2)

Digital Gauge for Testex Tape
SKU pcwi-INDICADOR-PERFIL-DIGITAL
A digital micrometer used with replica tape to give a numeric reading of surface profile/roughness depth for blasted steel or concrete.

Testex Replica Tape
SKU pcwi-MEDIDOR-RUGOSIDAD-CINTA
Replica (burnish) tape pressed onto a blasted surface and read with a micrometer to measure anchor-pattern surface roughness/profile depth.

High-Voltage Pulse Detector (Pulse Crest Meter)
SKU pcwi-DETECTOR-ALTO-VOLTAJE-PULSO
Checks the output voltage and sets detector voltage when a load is applied to the probe, to ensure accuracy and allow voltage adjustment where needed.

Low-Voltage Porosity Detector (Pin Hole Detector)
SKU pcwi-DETECTOR-POROSIDAD-BAJO
Uses the wet-sponge method to detect pinholes in coatings. The large probe head (230 x 40 mm) and wider sponge allow faster testing, with a headphone jack for testing in noisy environments (headphones not included), a seven-metre ground cable and clamp, and an instruction manual with calibration certificate.
