Even the smallest defect in surface coating – for example, through fissures, air bubbles or coating applied too thinly – can have catastrophic consequences. The PoroTest 7 operates with electrical voltage to detect microscopic defects (>20µm).
The PoroTest 7 helps you to locate pores, fissures and other faults in non-conductive coatings on conductive basis material such as steel, aluminium, concrete, etc. It therefore provides optimal protection from:
The PoroTest 7 is designed for use with boilers, pumps, tanks and other receptacles, but also for offshore installations, drilling rigs, ships or pipelines.
Holiday detector for detecting pores and holes in insulating materials on conductive substrates such as steel, aluminium, concrete etc.
