Plant production technology: tests and services

The development and application of modern, knowledge-based and practice-oriented testing and measuring methods characterises the work of the test engineers. The DLG-ANERKANNT (DLG-APPROVED) quality mark stands for neutrally tested and independently confirmed product quality.
