esz AG calibration &
metrology is one of the
leading and most modern
European metrology laboratories

In 1976, Dipl.-Ing. Siegfried Fleischmann – today’s Chairman of the Supervisory Board of esz AG – founded today’s esz AG as “Elektronik Service Zentrale”. Since then, the company has grown continuously, organically and in a structured manner – especially since 2003 – even in difficult economic times. By positioning itself on the market throughout Europe and striking a balance between growth and targeted expansion, esz changed its name from a GmbH to an AG at the beginning of 2009.

Within the scope of accreditation, esz AG is represented in the respective DKD technical committees. In this context, the company also chairs the Technical Committee on Measurement Uncertainty. esz AG is also involved in the VDI/VDE and plays a key role in the work on guidelines for the calibration of electrical measured values and in the development and implementation of a standardised data format for the exchange of measured values and data obtained in the course of calibration. In order to underscore its global recognition, esz AG has also supported the international committee of NCSL International (“The National Conference of Standards”) as a member since 2012. NCSL International is focussed on international metrological activities and cooperation. Both nationally and internationally, esz AG is represented with its experts in standardisation committees of the DKE (German Commission for Electrical, Electronic & Information Technologies in DIN and VDE), CENELEC (Comité Européen de Normalisation Électrotechnique) and IEC (International Electrotechnical Commission) in order to make an active contribution with its expertise in the field of measurement uncertainty, statistical evaluation and conformity assessment, and has even been entrusted with the chairmanship of a working group for the IEC. The confidence of the DAkkS in the competence of esz AG is not only confirmed by the auditors in the course of the accreditation assessments, but also by the appointment of our experts to the DAkkS Expert Council and the Accreditation Advisory Board of Division 5. The latter through our membership of the VUP (Association of Independent Testing Laboratories).

esz AG works closely with scientists from the national metrology authority PTB, the cooperation partner Supracon and the Swiss colleagues from METAS. Together, they have succeeded in achieving a mobile Josephson voltage standard for direct and alternating variables. esz AG is a pioneer in quantum calibration in industrial laboratories. By expanding and further developing its technology and its own products, esz AG can ensure that it can maintain its leading role in the market and continue to grow in the future.
