Permanent Reference Cell – Fontana 104C Cu/CuSO4

Fontana 104C Gelled Copper Copper-Sulfate – Permanent Reference Cell


Fontana Instruments offers new liquid gel permanent copper copper-sulphate reference cell to measure electrical potentials for corrosion engineers. This electrode is recommended for measurement of electric potentials at test stations, connecting to TR units and has contact points for surveying purpose.


Rugged ultraviolet and chemically resistant inert long ceramic tubing. Continuous moisture retaining capability with preheated uniform and controlled ceramic porosity. Especially liquid gelled mixture surrounding with copper coil reduces electrical resistance and no requirement of moistening and works at even high temperature. Excellent shelf life and highest sensing area allows measurements with stability
