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
REFERENCE electrodes

Besdata Technology Company Limited
Besdata Technology Co., Ltd is professional in supplying EEG
electrodes, EEG caps, EEG conductive gels and pastes. In addition,
We also provide standard and private label products, and customized
medical accessories on behalf of or together with third parties.
Besdata® EEG electrodes are made of a variety of electrode
materials( Gold coated, Pure Silver, Silver/Silver chloride,
Sintered Silver chloride) to meet different demands, we transmit
stable and clean signals for precise EEG measurements.
Unicare Silver/Silver chloride cup electrode is unique high
quality, made of pure silver and coated with silver chloride. has a
very low DC offset potential, minimal motion artifact and good low
frequency EEG response. Can be used many dozens of times and
maintain their quality performance characteristics. Even if the
layer of silver chloride is worn out, it would never influence the
stability of the measurement.
Besdata® Sintered Sliver Chloride is preferred for precise neural
signal detection. It provides top-of-the-line performance, being
excellent for DC and low frequency EEG
Besdata® EEG-caps offer up to 128 electrodes of various electrode
materials to meet the needs of both researchers and clinicians, we
could offer 20, 32, 64 and 128 channel as standard, Meanwhile with
customized channels to order.
Besdata® EEG conductive Gels and Pastes has been specially formulated for using with EEG caps and Electrodes. It provides skin preparation and conductivity which dramatically lower electrode-skin impedance, quickly stabilizing measurement, much more easy and convenient to use than the other.
Besdata® are continually expanding our capabilities to realize the
unlimited possibilities of capturing electrical signals of brain,
even the human body.
And we are always looking for new opportunities to expand our
network, Step by Step.
