eso GmbH was founded in 1977 as a family-owned company. On July 5, 2017, it became eso GmbH – A Kistler Group Company, part of the Kistler Group. With the acquisition of the world’s leading manufacturer of speed measurement equipment for traffic monitoring, focused on optical sensors and light barrier systems, Kistler expanded its existing portfolio of measurement technology solutions for improving road safety.
eso GmbH – A Kistler Group Company benefited from a global corporate structure and additional opportunities to tap new markets. In March 2021, eso GmbH fully merged with Kistler Instrumente GmbH.
The original eso headquarters in Tettnang /Allgäu was retained by Kistler Instrumente GmbH as a center for excellence, sales and service for speed measurement equipment. However, the production site was moved to the German headquarters of Kistler Instrumente GmbH in Sindelfingen.
