Abstract:

Two laboratory test bridges that use a comparison technique between a reference cell and a cell that has been exposed to marine foulants have been completed through their test stage. 17 10-cm. conductivity cells have been constructed from the 18 sets of purchased parts which were received. One cell failed during the high temperature firing process, however, six months after receipt 17 successfully completed the glassingfiring process. After successfully completing the firing process, these 17 cells were sent to an industrial plating firm where the exposed electrodes received a 5-mil platinum plating. This process was used to improve the conductivity cell stability and took approximately eight weeks to complete. Next, a waterproof connector and cable arrangement were designed and constructed and mounted onto the 17 cells. All 17 conductivity cells are to be pressure-tested to 500 PSI for one hour. 12 conductivity cells were then submitted for Ce-Cap anti-foulant impregnation. This anti-foulant is a tributyl-tin-oxide base.
