EDA Electrodes

These dry electrodes are designed for electrodermal activity (EDA) measurements—application of GEL101A isotonic gel (available separately) is required for EDA measurements to establish physiological ionic equivalency to the skin surface. The electrodes conform and adhere well to a variety of skin surfaces. Typically, they are applied around fingers to create a firm bond. These electrodes are also very suitable for attachment to the palm, wrist, toes or sole. These electrodes incorporate a gel cavity situated between electrode and skin surfaces that helps to stabilize measurements and reduce motion artifact. Use with LEAD110A or SS57LA/L unshielded electrode lead.

• Standard snap connection
