Reusable Snap-Button Electrode (Ag/AgCl), 12mm (outer) electrode diameter and 4mm or 8mm (inner) cavity diameter, 2mm cavity depth. Sensors can be used for a myriad of different applications including EEG, EOG, ECG, EMG facial EMG and EDA/GSR. 1 electrode per pack.
These Reusable Snap-Button Electrode (Ag/AgCl) have a 12mm (outer) electrode diameter and 4mm or 8mm (inner) cavity diameter. The depth of the cavity is 2mm. Sensors can be used for a myriad of different applications including EEG, EOG, ECG, EMG and EDA/GSR. Silver-Silver Chloride (Ag/AgCl) electrodes have outstanding electrical properties and are known for their low offset voltage, low noise and stability. These Snap-Button electrodes are reusable, non-toxic and can be cold sterilized.
Reusable Snap-Button Electrode (Ag/AgCl) are of type EL654 (4mm sensor diameter) and EL658 (8mm sensor diameter) from BIOPAC Systems, Inc.
Electrode Features
- Non-polarizable
- Sintered to increase contact area and to increase strength and stability
- Chloriding not required
- Reusable by 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
