Standard And Reference Electrodes Sintered Silver Silver Chloride
(AgCl) EEG Electrodes For Brain Wave Monitoring
Advantages of AgCl material EEG electrodes:
silver/silver chloride(Ag/AgCl) electrodes are made from very
finely powdered high purity silver and silver chloride. They are
mixed in a specific ratio and compacted into the electrode body at
very high pressures. The resulting pallet is relatively thick
(0.7mm to 1.0mm) and never needs to be rechloridized because it is
a homogenous mixture.
Sensor Features:
• Top-Performance,
• Less noise (from low frequencies)
• Less offset and less polarization and contribution to DC drift
than many other types of EEG electrode.
• The disc shape and bigger diameter provides fast, easy placement
• Less likely to move when properly applied
• Can be used with EEG-Paste (10-20), EEG-Gel or just using saline
in conjunction with the “Free-Cap”.
• The cable has a very stable connection to the electrode body and
therefore provides a long life of the sensor.
• Our (Ag/AgCl) electrodes are made from with a mixture of very
finely manufactured high purity silver and
silver chloride. The sintering process was made under very high
pressure but still provides a very thick layer
Wires Features
· PVC material and TPU material for selecting
· Shielding wire is optional
· 10 colors, Red, White, Green, Black, Grey, Brown, Blue, Purple,
Orange, Yellow.
Ag-AgCl electrodes made by BESDATA have superior properties,
they're made from a mixture of very finely manufactured high purity
silver and silver chloride, A careful proprietary process results
in a fine grain, homogeneous mixture of silver and silver chloride.
The mixture is then compressed and sintered into the various
configurations. A pliable silver wire is imbedded in the Ag-AgCl
matrix to provide electrical connection by soldering or other
means.
Unlike plated or chlorided silver, BESDATA Ag-AgCl electrodes are
homogeneous throughout. If the surface is damaged or contaminated,
a new surface can be exposed to restore the original performance of
the electrode.
Ag-AgCl electrodes are nontoxic because of their stability and
reproducibility, Ag-AgCl electrodes make excellent STANDARD and
