Shimadzu releases new non-contact UEP measurement instruments

Shimadzu Corporation has released the CF100 and CF110 underwater electric potential (UEP) measurement instruments, which provide highly sensitive UEP measurements without requiring physical contact with structures, to address corrosion and other issues affecting underwater structures.

 

An underwater electric potential is an electric field generated in water. By measuring the underwater electric potentials caused by corrosion, users can monitor corrosion and identify affected areas on structures.

 

The CF100 employs a board-type controller designed for integration into underwater robots such as autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs, underwater drones). The CF110 employs a benchtop-type controller designed for portability by divers or for use in test facilities.

 

 

UEP measurement instruments enable the non-contact measurement of underwater electric potentials even when marine growth is attached to the structure. Shimadzu has previously supplied customised versions of these dual-use (civilian/military) technologies to underwater robot manufacturers, engineering companies, resource exploration firms, and the Japan Ministry of Defense.  The company is now officially releasing standard mass-production models.

 

Since 2020, Shimadzu has also been offering the MC series of underwater optical wireless communication devices, which enable both high-speed transmission of large-volume data and low power consumption. These solutions support the digital transformation (DX) of ocean development activities conducted by companies and research institutions working in marine environments.
