This 30 inch Intermediate Extension Rod can be inserted between a standard reference electrode (RE-5, RE-5C, RE-7, RE-3A, Sponge Bottle etc.) and a “Side Terminal Electrode Extension” in order to further extend the distance between a reference electrode and a (side terminal) test lead connection.

For example, combining our 30 inch Extension Rod (Item #16101) with this 30 inch Intermediate Extension Rod (#16203) would result in a total rod length of 60 inches.

Multiple Intermediate Electrode Extension's may be used to increase total length.
