Porosity Detectors

PCWI Compact DC15 Porosity Detectors
A High Voltage DC Porosity detector also known as holiday detectors, spark testers, porosimeters and jeepers. These are used to ensure the longevity of coating systems by locating pin holes or holidays, air bubbles, and porosity in non-conductive (dielectric insulation type) coatings on conductive substrates, including concrete.
Applications
Suitable for Production Pipeline coating operations, Tank-work and Structures. Ideal for use on storage tanks, valves and pipelines
Housed in a fully portable ABS case, the Detectors deliver stabilised DC output of up to 30kV. Constant current source maintains applied test voltage. Full test current at low voltages (where it is needed most) when testing at low film builds (eg 150�m, as per AS3894.1-2002)
Incorporating momentary-on and continuous-on switches (mounted on the front panel), allowing the units to be switched on momentarily for safety, or to run continuously
No need to swap power supplies or change probes to change voltage - the detectors have clip-on battery packs which can be separately charged. Can operate off mains power (via the charger) during recharging. Fully recharged in 10 hours. Regulated DC output fully adjustable. Applied voltage and battery condition are continuously shown on the Liquid Crystal Display.
