We stay focused: on Quality, Environment, Security and Safety

For more than 50 years hopf Elektronik GmbH has been developing, manufacturing and selling highly-precise time reference systems.


Our modern production plants, precise measuring instruments, testing facilities and test equipment are the basis for the high quality of our products. Our in-house development from product design to marketing and direct sales allows us to guarantee a complete process flow and to meet the high quality requirements and standards of our customers. Manufacturing processes, commissioning and a 100% final testing of all our products are in accordance with the relevant regulations and standards. Customers' needs and satisfaction are our yardsticks and constantly contribute to the revision and optimization of our production processes.

It is therefore a matter of course that our management system for quality assurance is regularly audited and certified according the internationally accepted standard ISO 9001:2015.


Climate change and legal requirements result in increasing expectations of every company's environmental management. With certification according to the ISO 14001:2015 environmental standard, we are sending a strong signal and showing that we value the responsible use of the limited natural resources.


Besides ensuring a high product and service quality as well as comprehensively protecting our employees we also make sure to enshrine a continuous information and data security concept. Therefore hopf Elektronik GmbH has implemented an information security management system (ISMS) according to ISO 27001:2013 which considers aspects such as technical, organisational, personal and physical security.

From covering your valuable data over awareness of all hopf employees up to highly-reliable IT systems - we put all our effort into minimizing risks and protecting corporate values. Thereby we ensure to provide a high availability of our products and services to our customers.


Nevertheless, highest quality is not only important regarding our processes and products. As every single employee of our company plays a key role to hopf's success, precautions against accidents and work-related physical complaints up to work or occupational disability are subject to continuous reviews and adjustments by qualified personnel and safety experts.

Therefore, we minimize the operational risks for our employees and ensure comprehensive, state-of-the-art occupational health and safety which is confirmed by the certification according to ISO 45001:2018 (formerly OHSAS 18001).
