HD-03 Porosity Holiday Detectors are employed in the non-destructive detection and location of pinholes, bare spots or thin points in protective coatings applies for corrosion protection over metal and concrete (conductive) surfaces.
With corrosion an extremely costly and disruptive worldwide problem, preventative determination becomes essential.
For newly constructed tanks, pipelines and other installations, where corrosion prevention coatings have had to be applies, specifications will normally call for a specific coating to a specific thickness. By using a our Detector to verify the competency of the sealing coatings, the contractor can be assures that his coatings responsibility has been met. In terms of cost effectiveness, with the low capital and operating costs of the Detector, the contractor will have some protection from claims at a very low price.
Detection Principle: electric spark leak detector is through various conductive substrate surface coating with a certain amount of pulse pressure, such as anti-corrosion layer for a thin, leakage metal or leak pinhole, when pulse pressure passed, forming air gap breakdown and produce spark discharge, at the same time give alarm circuit sent to a pulse signal, make alarm sound alarm, so as to achieve the purpose of detection of anticorrosive coating.
