Ag-AgCl Shielded Electrode, 12.5 mm diameter housing, 8 mm contact area, includes 1 meter lead

terminated with two 1.5 mm female Touchproof sockets for connection to the SS1L. The gray lead

plug is for the electrode contact; the black lead pin plug is for the lead shield.

Series reusable electrodes are permanently connected to 1-meter leads and terminate in standard 1.5 mm female
Touchproof sockets for direct connection to the SS1L shielded electrode lead adapter.  Use shielded electrode
leads for minimal interference.  The unshielded electrode leads work best as ground electrodes.  Typically, one
biopotential input requires two shielded electrodes for signal inputs and one unshielded electrode for ground.
