LIDA® Rod Anodes
LIDA® Rod Anodes are comprised of a titanium substrate with a mixed metal oxide coating. The mixed metal oxide is a crystalline, electrically-conductive coating that activates the titanium and enables it to function as an anode. Standard length of LIDA® Rod Anodes is 4 ft., but they may be custom cut to virtually any length.

LIDA® Rod Anodes are available in the following diameters: 1/8 in. 1/4 in. 1/2 in. 3/4 in.

Anode coating may be selected to match freshwater, brackish water, seawater, coke, or sand environments.

LIDA® Rod Anode Life
Due to the extremely low consumption rates and dimensional stability of mixed metal oxide anodes, the electrical resistance of LIDA® Rod Anodes remains essentially constant with time.

The high current density capacity of LIDA® mixed metal oxide anodes has the added advantage of allowing high current overloads for initial polarization without causing harm to the anode.
