Established for over forty years, PSM Instrumentation, based in the UK, is a specialist in the design, manufacture and supply of marine control instrumentation and marine protection systems for the marine transportation industry.


In March 2016, Scanjet Holding AB acquired PSM as a strategic partnering investment. Combined, the two companies offer a more comprehensive product range that completely fulfils the concept of Intelligent Tank Management (ITAMA), providing a single source total package for the marine market.

In August 2022 Scanjet was itself acquired by Alfa Laval

We offer a total package of advanced marine instrumentation software systems and application solutions for designers, ship builders and end-users, to ensure vessels operate efficiently and reliably and are compliant with legal, safety and environmental regulations.

Working with engineers and designers, fleet operators, and maintenance and repairs companies, and understanding their requirements, has enabled us to develop products and systems dedicated to meeting their specific applications.
