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.
BIOPAC EL250 series and EL650 series reusable electrodes incorporate a variety of features which improve biopotential recordings:
- Sintered to increase electrode/electrolyte contact area
- Do not require chloriding
- Reusable via resurfacing
- High stability recordings, to DC, when used with chloride salt gel electrolyte
- Electrolyte gel cavity reduces artifact due to electrolyte/electrode motion and minimizes electrolyte dissipation/drying over long-term recordings
