HD-101 Holiday Detector Non-Destructive Coating Pinhole Detector for Metal Concrete

HD-101 Holiday Detector Non-Destructive Coating Pinhole Detector for Metal Concrete

1.OVERVIEW

HD-101 Holiday Detectors are employed in the non-destructive detection and location of pinholes, bare spots or thin points in protective coatings applies for anti-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. Meanwhile, as well as apply in porcelain enamel industry.

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.

3. Measurement principle

HD-101 Holiday detector provides certain impulse-voltage on the surface of protective coating or painting, where covered above the metal material basement. If the protective layer exists pinholes or the coating is too thin, the detector will release sparkle and give impulse signal to alarm component. The alarm component will beep and beep, and point out harmful points to the operator.

4. Configuration

HD-101 Holiday detector is constituted of main unit, high voltage generator and probe brushes.
