ISOTEST 4S

ISOTEST 4S is indispensable in the area of passive corrasion pratection. 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 contral, to reducing stoppage times and avoiding interruptions to production and subsequent repair costs. 

Coating thicknesses fram a few hundred micrametres to several millimetres can be tested for pores, cracks or scarcely discernible transport damage by means of short high voltage impulses
