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.

 

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

 

Electrical Specifications

  • DC offset Voltage (biaspotential): 180 µV
  • Drift: 25 µV / h (at constant temperature)
  • Noise: 1 µV P–P (0.1 – 1 kHz with 60 Hz filtered out)
  • Polarization (counter EMF): 2 – 4µV at 0.1 µA
