Porosity Detectors, Digital Portable Holiday Detector,

detect range:30um~1mm, RHD-20

RHD-10/20 Porosity 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
