Scintillograph, Porosimeter ARW-DJ

Porosity detector "Holiday Detector"

The ARW-DJ scintillograph is a porosity detector with a output voltage up to 30kv used to detect the quality of the metal coating for an anti-corrosion process. This meter can be used with different types of coating, as a glass covering, plastic reinforced with glass, tar, rubber coating and so on.
The instrument is equipped with a rechargeable Ni-MH battery power supply, it is light and small in size and is particularly suitable for the operation of the field. Indispensable to detect the quality of the antibody coating on a ferrous metal basis, it can be widely used in many sectors between chemistry, oil, rubber and ceramic, thanks to its sophisticated design and stable and reliable performance.

Applications

Used for detecting the degree of porosity on insulating type protective coatings in various applications on conductive substrates where anticorrosive coatings play a very important role. Particularly used in the control of coatings on pipes (Pipeline), tanks, valves, gas pipelines, oil pipelines, in the petrochemical sector and in the analysis of porosity on enamels and protective paints.

Test Principle and method

The ARW-DJ Porosity Detector is composed of an instrument body able of supplying a constant and user-adjustable voltage. Through an insulating handle connected to a brush, voltage is transferred to the coated material to be inspected with the aim of verifying any defects, imperfections, porosity or lack of coating present on the surface. If pinholes exist in the protective coating or the coating is too thin, the detector will release a spark and provide an audible signal alerting the operator of the defect found.
