Our Services

We attach great importance to the highest quality of service as well as fast response and throughput times. Our primary goal is to enable seamless manufacturing processes, which we ensure, for example, through mobile calibrations directly in your factory in order to keep downtimes as low as possible. In addition to the calibration service, we also offer a repair service and individual custom-made products.

Calibration Service

We offer you a comprehensive calibration service for electronic torque / angle tools. We check the measured variables torque and angle of rotation on our state-of-the-art calibration system. It goes without saying that our measuring equipment is calibrated by a recognized DKD laboratory and can therefore be traced back to national standards. We also carry out calibrations directly in your factory.

Repair Service

We offer the complete repair service for torque / angle tools as well as the maintenance of electronic torque / angle tools. We take care of the replacement of defective batteries, functional tests of components and repairs of control boards. We work out cost estimates for you and always carry out our work on time.


Do you have a special application? We help you to find the optimal solution. Special tools and special software packages are developed and manufactured according to your requirement profile. For example, we offer the individual connection of your new tools to higher-level computer systems or PLC controls - to name just one example of many possible. We are already looking forward to your challenge!
