IMA Tin EEG flat sensors are 9mm flat electrodes and a 1.5mm (.059) DIN safety plug.
The
special designed safety plugs offer more space between safety plugs even at
narrowly placed sockets and a better fit also with wider (worn out) sockets at
some head boxes
IMA
electrodes with Teflon 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.
