Collectively, the pellet, wire, and pin form an electrode (Figure 3-4).

Surrounding each electrode pellet is a sponge that, during operation of the GSN 200,
is wetted with liquid electrolyte. The pellet and sponge are set inside the bore of a
plastic pedestal consisting of three parts that snap together (Figure 3-5).

The wetted sponge protrudes from the one end of the pedestal and the lead wire
emerges from the other end through a small hole in the pedestal cap.
By definition, a sensor (Figure 3-6) consists of a pedestal and an electrode.
