ISOTEST 4S plus

SOTEST 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.
