UFS offers a Myron L digital conductivity controller pre-installed in a metal enclosure. This controller will work with either anodic or cathodic paint systems, and has a range of 0-20 milli-Siemens/cm (same as 0-20,000 milli-Mho/cm). It has a set of dry contacts that close on rising conductivity so a DI water valve can be turned on to add water and dilute the anolyte conductivity to below its set point.
