Compact DC High Voltage Pulse Porosity Detector - Holiday Detector


The Compact DC High Voltage Pulse Porosity Detector - Holiday Detector is no longer available and has been replaced by PoroTest 7.
Click here to see the PoroTest 7.


Measuring Ranges:
Model DC15: 0 to 15,000 Volts
Model DC30: 0 to 30,000 Volts

Resolution: Model DC15: 10 Volts
Model DC30: 10 Volts
The DC Compact™ electric Porosity Detection - also known as Holiday Detector - is ideal for the detection of pores and faults in dielectric (electrically insulating) coatings such as paint, enamel and plastic coatings on all metals, also on concrete.

The material-friendly DC Compact™ detector has proved itself indispensable on the production line and in the field, for instance in the production of pipelines, storage tanks, pipelines, enameled construction parts for the chemical industry, etc

Applications
  • Used for detection of coating porosity (pin-holes, or holidays) in dielectric (insulation type) coatings on conductive substrates, including concrete.


  • 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┬Ám - 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 run continuously.


  • No need to swap power supplies or change probes to change voltage - the Detectors have clip-on battery packs that can be separately charged. Can operate of 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.
