The compact holiday detector is a high voltage DC porosity detector also known as holiday detectors, spark testers, porosimeters or jeepers. These are used to ensure the longevity of coating systems by locating pin holes, air bubbles and porosity in non-conductive coatings on conductive substrates, including concrete.

• Light weight ABS case
• Momentary on switch allows for automatic shut off
• Digital display of applied voltage with integral battery condition indicator
• Voltage ranges of 0-15KV or 0-30KV, fully adjustable
• Regulated DC voltage
• Clip on battery pack
• Constant test current
• Sensitivity control
• Overcharge protection
• Single power supply
• Earphones for noisy environments

Applications:
Used for detection of coating porosity (pinholes or holidays) in dielectric (insulation type) coatings on conductive substrates, including concrete. Suitable for production pipeline coating operations, tankwork and structures. Ideal for use on storage tanks, valves and pipelines.

The compact pulsed porosity detector is fully adjustable, has regulated “pulsed” output up to 20KV and 40KV. All pulsed 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.

• Light weight ABS case
• LED digital display of applied voltage
• P20 and P40 holiday detectors are available in industrial and pipeline kits. The P60 is available only in and industrial kit.
• Voltage ranges of 2,000 to 20KV or 40KV and 10KV to 60KV, fully adjustable
• Clip on battery pack
• “Wet” or “Dry” condition sensitivity control on P20 and P40
• Overcharge protection
• Single power supply
• Earphones for noisy environments
• Low battery condition indicator
• The pulsed 60KV model is the only portable battery operated model on the market capable of generating voltages from 10,000to 60,000 volts

Applications:
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: 6-1000mils (150-25,000um) with P40, and even thicker with P60
