Coatings / coverings of the most diverse kinds can be tested rationally and reliably to detect pores and pinholes.
Precise adjustment and control of the testing voltage guarantees testing according to relevant regulations and customer specifications. The pulsed testing voltage allows the application of the capacitive grounding. This way of grounding renders the possibility - in contrary to the DC mode – of the testing of completely coated pipes. No direct contact to the metallic part of the pipe is necessary.
The intelligent microprocessor control system guarantees the highest degree of measuring certainty and fault tolerance. The testing voltage is adjustable from 5.0 kV – 30.0 kV in 2.5 kV steps and is constantly monitored by the electronic controller.
