What we do

Innovation has always been of great importance to us. It not only involves the development of new products and technologies, but also the design of new or improved production technologies and production methods. Innovation means that we are always a step ahead of the rest. To achieve this we draw back on years of experience and tradition, which always opens new doors for us.

Calibration and re-calibration –
the reason for this

Newly calibrated measuring instruments with regular re-calibration strengthen the relationship of trust with the customer and guarantee accurate cost accounting and consumption estimates. All these factors contribute to reducing costs. The recalibration keeps the operating costs of the measuring instruments low and extend the service life of the instruments. A calibration certificate in accordance with EN 17025 certifies national recognition, creates confidence in the internationally recognized test mark and certifies the quality of your measuring instruments and your technical skills. Do you have special requirements or measuring points that you would like to have tested or inspected? Then our expertise and know-how are at your disposal.
