Roughness measurements on a wide variety of surfaces and the determination of surface and line-based characteristic values is an important quality assurance process for high-quality components. The CONSIGNO SR offers a simple option for contactless and reliable roughness measurement, even on the smallest surfaces or in places that are difficult to access. Thanks to automatic parameterization of the measurement process and standardized and standard-compliant evaluation, roughness measurement can be carried out with minimal training, even on complex components.
