Marine Electric Systems has supplied the Navy with salinity cells, indicators, panels, meters, and detectors since 1942, and remains the prime and sole source supplier on much of that equipment.
Aboard a Navy ship, a small amount of seawater in the boiler feedwater is a serious problem. Salt contamination corrodes tubing, scales heat transfer surfaces, and can take a propulsion plant out of service. Detecting contamination early is a condition of staying underway rather than a convenience.
Marine Electric Systems has supplied the equipment that performs that detection since 1942. Our salinity cells, indicators, panels, meters, and detectors monitor boiler feedwater, condensate, and seawater systems across surface and subsurface platforms, and we remain the prime and sole source supplier on much of that equipment for the U.S. Navy.

This has never been a large market. It is a specialized product line that has to function every time, on platforms that have been in service for decades, supported by a manufacturer that has not discontinued it. We design, build, and test these products at our facility in South Hackensack, New Jersey, alongside the circuit card assemblies, wiring, and machined components that go into them.
Because the product line has remained in production continuously, we are also able to support units that have been in the fleet for many years. When an older indicator or panel fails and a replacement is no longer available through normal channels, we can repair it, rebuild it, or manufacture a replacement to the original requirement.
If your program relies on salinity or water quality monitoring equipment, or you are sourcing replacements for legacy units, we can help.
