The gold EEG flat ear clip sensor is 8mm spring loaded flat disk eeg ear clips terminated with a 1.5mm (.060) DIN safety plug. Lead wires approximately 48 inches in length. Gold composition
IMA electrodes with teflon coated wiring have 144 silver strands per lead.
IMA electrodes with silicone coated wiring have 7 silver ribbons combined with Kevlar for strength, dipped in silicone coating.
Each type : 48” = 1 ohm resistance out of 4,000 ohm from scalp.
Care:
Do not soak in water (creates corrosive brine).
Wipe with alcohol after each use.
For
heavy discoloration or build up on silver electrodes use toothpaste
(not gel), comet or ajax, wipe gently and rinse with warm water.
For
gold plated electrodes use alcohol or toothpaste (not gel), be very
gentle, rinse only - do not soak. Scratched plating is the most common
cause of failure for gold electrodes.
Take
care not to crimp the wires or pull at wires from the ends, this is the
most common reason of failure for all electrode wiring.
