Measuring and controlling in accordance with all rules of the art and the laws of physics

When the task at hand is the measuring, controlling and regulating of processes, we provide you precisely the suitable technology. At our Center of Competence Martens in Barsbüttel, near Hamburg, we develop and produce robust and reliable components for the demanding process and industrial technology. In this regard the seal of quality "Made in Germany" not only characterizes the quality of our technical solutions, it equally stands for the innovative strength of our company. There is a good reason why the delivery and manufacturing program ranges from digital indicators, to measuring transducers and evaluating devices, and extends to sensors – the entire spectrum of modern analysis and industrial measuring technology. We satisfy customer-specific requirements with especially adapted devices. The resulting versatility of our products is reflected in a broad range of applications: From building technology and plant engineering to the food industry, our products measure, control and regulate countless technical processes. Virtually any physical variable can be measured, recorded and evaluated. And one significant variable can be materially felt: The quality. We consider care to be the most important additional matter, of which our products are manufactured.

"The only measurement that a human being can execute on his own is simple counting. For everything else he needs technical support. And for more complex topics, gladly also a discussion with our technology organization."
