ISOTEST 4S plus is indispensable in the area of passive corrosion protection. Non-destructive high voltage testing of the most diverse coatings and corrosion protection materials has proved itself again and again over long periods of time. The test, prescribed by many works' specifications and standards, has made a successful contribution, within the framework of quality control, to reducing stoppage times and avoiding interruptions to production and subsequent repair costs.
Coating thicknesses from a few hundred micrometres to several millimetres can be tested for pores, cracks or scarcely discernible transport damage by means of short high voltage impulses. The short action time of the impulses, which treats the material gently, makes it possible to test with reserves of energy, which, in turn, guarantees the stability of the selected test voltage even with dirty or damp surfaces.
Defective areas can be clearly distinguished, whether it be with externally or internally coated tubes, rubber coated containers, seams in plastic, fully sheathed fittings or machine parts... everywhere where non-conductive coatings are overlaid on conductive materials (e.g. metal, wet concrete) or where non-conductive coatings have an underlay of conductive materials (e.g. plastic seams in tubing or containers).
A large number of accessories are available for a wide range of applications. Test electrodes for the most diverse shapes of objects and coatings are complemented by components for the using of different earthing possibilities- including capacitance earthing to test fully coated components.
