Marine Calibration
At JBA Calibration Services we specialise in the marine industry.
Onboard Marine Calibration Services UK & Worldwide
At JBA Calibration Services, we specialise in onboard marine calibration services for the shipping and maritime industry across the UK and globally.
Our experienced marine technicians perform precise, traceable calibrations directly onboard your vessel, eliminating the need to remove critical equipment and send it ashore.

- Rapid Emergency Response – often within 1–5 hours in UK ports
- OEM Approved calibration procedures
- Full traceability to national standards
