IMA Solid Silver Flat EEG sensors are solid cast pure silver (99,9%), polished 9mm flat electrodes and a 1.5mm (.059) DIN safety plug.
The special designed
safety plug 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.
