Gel for EDA (GSR)/SCR

Only GEL101 (a solution designed to mimic the salt concentration of sweat) should be used with reusable skin conductance (electrodermal activity) recording electrodes. GEL101 electrode paste is specially formulated with 0.5% saline in a neutral base. Similarly, EL507 is BIOPAC's only disposable electrode designed for use in skin conductance measurements. EL507 also uses an isotonic recording gel, similar to GEL101. The use of gels formulated for other biopotential measurements leads to an overestimate of the tonic skin conductance level and violates standard recommendations for methods of monitoring electrodermal activity.
