How does Roughness Testing work and when is it necessary?

Roughness Testing is a non-destructive testing method used to determine how rough or smooth a surface is. We apply a simple yet advanced instrument, which measures resistance with a stylus. Based on this outcome we can determine the resistance and thus the roughness.

Roughness Testing proves to be the perfect solution in a number of situations. For instance, when applying coating on a material for which its manufacturer has recommended a certain roughness in order for it to adhere optimally to a surface. Without Roughness Testing the coating may detach, causing high repair costs later.

Sometimes a surface needs to be as smooth as possible, for example when corrosive materials are involved or materials used in the food and dairy industry.

In both cases remaining residue is the problem. Roughness Testing can guarantee that a surface is smooth enough to prevent deposits.
