Online Porosity Holiday Detectors/High voltage Pinhole Detector HD-130

HD-130 on-line holiday detector can work continuously adopting AC power supply, high-voltage control switch and external alarm lamp.

HD-130 Porosity Detector 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.

Application

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 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.

It is a special instrument for detecting the quality of metal anti-corrosion coatings. The instrument can be used to detect the quality of glass lined, FRP, epoxy coal asphalt and rubber lining coatings with different thicknesses. When the anti-corrosion coating has quality problems, such as pinholes, bubbles, cracks and cracks, the instrument will send out bright electric sparks and sound alarm at the same time.
