GreCon thickness gauges contribute in ensuring the optimal use of raw materials and to ensure a fault-free product quality. Thickness fluctuations and deviations from the nominal value are detected in time. Waste of material, losses in quality for the processing of the materials and unsatisfied customers are avoided. Besides, feedback from the measuring results can be used to directly influence the production process.
