Surface inspection.

Would you like to measure the surface roughness of a component?

We carry out a surface test to characterize surfaces and their properties as well as to check the protective function of the surface coating (e.g. corrosion protection, UV / light protection, mechanical stress, media resistance, layer thickness).

We check the surface resistance and determine surface defects.

If components are further processed in the manufacturing process, defects in the material not only lead to visual impairments but also to impairment of the later function (function-critical defects). Especially with high-gloss, polished or lacquered surfaces, small optical defects can be very irritating and lead to complaints about entire assemblies and the associated high scrap costs.

We offer a wide range of test methods to characterize surfaces, their coatings and properties, to determine surface defects and surface resistance:
