We manufacture all of our instrumentation at our dedicated 20,000 sq. ft. facility in Aldermaston, in the UK.

Quality Management and investment in design

Our sensors are built in clean, HEPA filtered laminar flow environments which achieve ISO Class 7 cleanliness (equivalent to FED Class 10,000).
The most critical mechanical components are designed and manufactured in-house using the latest CAD/CAM technology and are machined on our 4 state of the art CNC milling machines, including 2 robotically tended 5-axis machines. This allows for reduced lead time, tight process control, and a lean design cycle due to our ability to rapidly develop and refine product prototypes.

Electronic assemblies are built to meet the standards of IPC-A-610, for quality and reliability.

Robust Supply Chain Management

Those parts that aren’t manufactured in-house are sourced from a carefully selected number of trusted, specialist suppliers. Critical parts are dual sourced for sustainable scalability and resilience. The majority of suppliers are based in the UK and are accredited to ISO9001, AS9100 or ISO13485. All purchased parts are subject to our meticulous QA processes before being passed to the production team.

Quality Assurance

As part of our dedication to quality, all instruments are thoroughly tested at multiple stages throughout their assembly, from individual components to completed products, from dimensional checks to full functional tests, from detailed noise analysis at our dedicated local Vault to long term environmental soak testing.

Before any order leaves our facility, it is subjected to a full independent ‘user-experience’ system integration test, followed by a final QA sign off.

ISO9001 Certification

Güralp Systems has been certified to ISO9001 for more than ten years, and achieved the ISO9001:2015 in 2018 with no nonconformances.

Our certification recognises our quality management system covering the design and manufacture of low noise broadband seismometers, accelerometers, digitisers and networking equipment for science and engineering. Software design and development.

These high standards are maintained through regular, rigorous internal and external audits.


Over the last 35 years, Güralp has supplied thousands of seismic instruments, including borehole and ocean bottom systems, to customers across all continents and in a range of sectors:
