Our team checks all the equipment during the development and during the production process and also ensures that all devices comply with national and international guidelines and standards. This usually includes low voltage directive, electromagnetic compatibility, RoHS and the Reach directive. Quality and continuous improvements in the processes are essential elements in the work of PeakTech.

OEM and Innovations


Even if we do not already have a product in our program, we always have an open ear for your product proposals. Depending on complexity, new products can be developed and manufactured in a short time, so that they are available in our sales program within a few months. Also for your special projects or inquiries for OEM products (with your own company logo) we offer you our full support and enable a realization even in smaller quantities.



All PeakTech devices are delivered calibrated directly at the factory. This means that the accuracy of the measured value display of each function (measuring devices) is checked, compared and approved with the specified tolerances. Only flawless devices are approved for sale.

Measuring devices can lose accuracy due to daily use, transport and changing environmental conditions. We therefore recommend re-calibration after one year.
