Teq-Trode Silica-Carbon Electrodes (SC) Like the Foam Ovals, they are designed for long periods of continuous use or repeated electrode placement. Instead of a pigtail connection, the electrode cord pin is inserted directly into the electrode itself. A little less flexible than the Foam Ovals, the Silica-Carbon uses the same highly conductive adhesive gel for multiple use and/or multiple placement.

Each SC2-4 package contains four 2 inch (1.75 x 1.5 inches) electrodes.
