Portable and Immersion References Selection Guide
Maintenance-free portable reference electrode can be used in place of a standard liquid-filled portable reference. They are available with either gelled Cu/CuSO4 or gelled Ag/AgCl elements. The termination is the standard 1/4-20 stud end with a knurled finger nut. These electrodes can be ordered with a temperature indicator bonded to the electrode body and/or antifreeze added to the gel so that the electrode will not be damaged if exposed to sub-freezing temperatures.

Immersion Reference Electrodes
Immersion reference electrodes are used in water tanks, waterfront structures and other
applications where the electrode is fully immersed. They are available with gelled elements and
custom wire length terminations. Optional features include anti-freeze and a mounting magnet.
Seawater Reference Electrodes
are intended for either portable or permanent installations on marine structures immersed in
clean full strength seawater. They are available with dry-type Ag/AgCl or Zn elements.
Terminations include wire or stud ends. The housing design allows them to be directly
cemented to 1/2" PVC conduit.
Custom Immersion Products
Electrochemical Devices, Inc. works with design and corrosion engineers to produce reference
electrodes for those applications where our standard models may require modification.
We do not charge design fees for this service and in most cases the custom product is priced
comparably to a similar standard product.
