Elektrophysik pinhole detector inspects coating by voltage. Small defects (20 m) can then be detected in the surface coating. Even small defects in surface coatings can have fatal consequences, so careful testing with the right pinhole detector is critical. During pinhole inspection of surface coatings, urgent action is required when only the smallest defects are found. Small defects in the coating are enough to cause significant damage. ElektroPhysik's PoroTest7 pinhole detector is an indispensable aid in finding voids, cracks and other defects in non-conductive coatings on conductive substrates.
　　Using the pinhole detector, you can inspect surface coatings to prevent:
　　Corrosion from outside and inside
　　Damage due to minor coating defects
　　Damage to highly fragile foods
　　Dangerous chemical reactions
　　Expensive recoating due to undetected defects
　　Detailed application examples of elektrophysik pinhole detectors:
　　Prevention of external factors:
　　Examples range from offshore plants and rigs to ships and pipelines. These are always exposed to adverse environmental factors. The coating's small damage is enough to bring the steel substrate into contact with moisture and then start rusting. Pinhole detection therefore prevents corrosion and prevents subsequent damage.
　　Content protection:
　　Boilers, pumps, tanks and other containers are internally coated to prevent food from contacting the metal of the container. Immaculate coatings are also the basis for storing and transporting corrosive substances to prevent contamination of cargo or dangerous reactions.
　　Elektrophysik pinhole detectors detect and subsequently eliminate defects and failures in coating application. Such deficiencies include:
　　Bubbles formed during use
　　cracks formed during hardening
　　Coating too thin
　　Coating applied too thick may eventually crack or fracture during curing
　　PoroTest7 series by elektrophysik
　　Even the smallest defects in the surface coating-for example, cracks, bubbles, or coating too thin-can have disastrous consequences. PoroTest7 works at voltage to detect microscopic defects (20 m).
　　PoroTest7: Improving the safety of coated surfaces
　　PoroTest7 helps you locate pores, cracks and other defects in non-conductive coatings on conductive substrates such as steel, aluminum, concrete, etc. Therefore, it provides the best protection:
　　Internal and external corrosion
　　Secondary damage due to minor coating defects
　　Damage to highly sensitive foods
　　Dangerous chemical reactions
　　Costly recoating due to undetected defects
　　PoroTest7 is designed for boilers, pumps, tanks and other vessels and can also be used on offshore installations, rigs, ships or pipelines.
