Ag-AgCl Reusable

Ag/AgCl Electrodes for Biopotential Recording

BIOPAC provides a series of resuable Ag/AgCl electrodes for recording biopotentials.  Silver-Silver-Chloride surface electrodes are offered with 4 or 8 mm, shielded or unshielded, snap, Touchproof, RT, or gel hole options.el654.jpg  reusable silver-silver chloride electrodes

BIOPAC EL250 series and EL650 series reusable electrodes incorporate a variety of features which improve biopotential recordings:

  1. Non-polarizable
  2. Sintered to increase electrode/electrolyte contact area
  3. Do not require chloriding
  4. Reusable via resurfacing
  5. High stability recordings, to DC, when used with chloride salt gel electrolyte
  6. Electrolyte gel cavity reduces artifact due to electrolyte/electrode motion and minimizes electrolyte dissipation/drying over long-term recordings
