Biopac Systems Inc. SS2L BSL Shielded Electrode Assembly Lead Set

This was surplus from a college.  It is not in its original packing and it looks like it is unused to me, but I don't know for sure.

The SS57LA EDA/GSR Lead connects to a single input channel to record electrodermal activity (changes in skin conductance) or, with modified setup, skin resistance from two EL507A disposable dry electrodes with GEL101A isotonic gel. The EDA/GSR Lead delivers accuracy over its specified range to within 5% with no calibration required. This disposable setup is an alternative to the reusable SS3LA EDA (GSR) Transducer.
