Portable Half Cell – Submersible Ag/AgCl Reference Cells – Fontana 103S

Portable Marine Service Reference Cell – Silver/Silver Chloride


Fontana Instruments offers new portable silver -silver chloride reference cell to measure electrical potentials for corrosion engineers in marine services. This electrode is recommended for measurement of electric potentials between contact points for surveying purpose.


Rugged ultraviolet and chemically resistant inert ceramic tubing especially embedded into PVC body with several holes makes easy survey in the sea right from sea shore to deep sea survey. Continuous water retaining and draining capability for the ideal survey at all time. For deep sea water applications, reference cells are fitted with insulated cable along with dummy weight and nylon rope to float in sea water.

Specially made ceramic with preheated uniform, controlled ceramic porosity assist silver- silver chloride wire reduce electrical resistance and no requirement of moistening. Excellent shelf life and highest sensing area allows measurements with stability.
