The Skin Conductance Electrodes (also called Galvanic Skin Resistance electrodes) are used with the NeXus Skin Conductance Sensor. They are included with the Skin Conductance Sensor
and consist of Ag/AgCl and are embedded in Velcro straps.
These electrodes can be used 50-100 times. You'll notice that they're worn out by a deterioration in signal quality. You can also notice this by the electrodes themselves, because the underlying material of the electrodes will become visible and some cases white spots may appear.
Skin Conductance Electrodes are packed in sets of 2.
