Measurement Engineering
Based on our numerous R&D projects for technology leaders, we have an excellent measurement infrastructure. Our experienced staff will advise you in advance on the measurement design in order to prevent unnecessary or incorrect measurements, to capture and process data efficiently, and enable validation in the context of modeling and simulation. Thus, nothing stands in the way of a successful project execution through fast, cost-effective and correct measurements.
