Disposable GSR/EDA Electrodes (EL507A)

These disposable snap electrodes are designed for electrodermal activity (EDA/GSR) studies. It is good practice to use these electrodes (EL507A) explicitly for EDA/GSR studies (see note below). These latex-free electrodes conform and adhere well to fingers. The disposable GSR/EDA Electrodes are ungelled (dry). Use with unshielded electrode lead (see related products below). Please add Isotonic Electrode Paste (114g) for EDA/GSR (GEL101A), as the electrodes do not come pre-gelled.

• Standard snap connection
• Ag/AgCl contact
• Strong adhesion
• Latex-Free
• Size: 27 mm wide x 36 mm long x 1.5 mm thick
• Contact Diameter: 11 mm
• Contact Area: 95 mm²
• Gel Cavity: 16 mm dia x 1.5 mm deep

Important Note: For electrodermal activity (EDA/GSR) studies it is important to use isotonic gel with a similar (isotonic) chloride salt content as the skin surface. Other gels, pastes and creams will potentially hypersaturate or hyposaturate the eccrine glands. For dried-out electrodes, use GEL101 (see related products below).
