Ear Electrodes (for Electro-Caps)

These earclip electrodes (E5) from ECI (Electro-Cap International) are made with pure tin cup electrodes. They come attached to a 48" (122 cm) lead wire and terminate in a DIN 1.5mm touch-proof (TP) socket (female connector). The plastic spring-clip back is used to hold the electrode in place and allows for additional patient comfort. Different earclip electrode cup sizes are available (6mm and 9mm).

One pair of pure tin cup earclip electrodes (one blue and one white) per pack.

Technical Specifications

Application Note

Ensure the contact material of the earclip electrodes and the contact material of your EEG surface electrodes are the same. Different contact materials will introduce unwanted drifts and noise due to differences in the galvanic series.

Application Instructions

1. Clean and degrease the skin with appropriate skin prep paste to lower impedance.
2. Remove residues of prep paste with a damp cotton ball or gauze.
3. Clip earclip cup electrode to subject's earlobe.
4. With a plastic syringe, fill the earclip electrode with conductive ECI Electro-Gel.
5. Connect the Plastic Earclip Electrodes to the biosignal amplifier equipment.

Note: After each use, clean the electrode with a damp cloth and mild detergent, making sure not to immerse the electrode in the cleaning solution. Then, carefully wipe with a suitable disinfectant.
