Why are corrosion testing systems needed?

Many products and their materials are freely exposed to today's environmental influences. Since the quality assurance of products and their reproduction play an increasingly important role in today's world, very high demands must also be placed on the testing systems.

So-called corrosion testing systems are used to accelerate the corrosion process. These can display the course of corrosion in fast motion using various methods.
