Part Ag-AgCl Adhesive/Disposable Electrode Type
EL506
Alternative
for band
electrodes
This unique disposable strip electrode is designed for bioimpedance applications. The electrode is
silver laminated on medical grade cloth, with industry-standard medical grade adhesive, medium
tackiness. The silver-silver chloride (Ag-AgCl) electrode provides accurate and clear transmission
of surface biopotentials and is latex free.
Strip length: 254mm
Conductive element width: 6.35mm
Adhesive width: 23.5mm
Advantages of the Strip Electrode
:
Combines the convenience of standard snap (spot) electrodes with the signal to noise,
equipotential and current diffusion performance of band electrodes
Less obtrusive than band electrodes--easier for subjects to move and breathe
Ergonomic advantages of snap (spot) electrodes
Diffuses currents similarly to band electrodes (reduces current density)
Provides voltage measurements through a well-defined equipotential plane
Adjustable size—cut the 25cm strip to the desired size without affecting signal transmission
Snap lead connection
Peel-and-stick convenience
Disposable
EL507
Designed for electrodermal activity studies and are pre-gelled with isotonic gel. The latex-free,
MRI-compatible electrodes conform and adhere well.
Wet Gel: 0.5% Chloride Salt
Contact area: 1 cm
Size: 2.5 cm x 4.5 cm
Snap: Stainless Steel
Backing: Foam
EL508
These disposable, radiotranslucent electrodes are pre-gelled.
Use with LEAD108. (See MRI use information for EL508 and EL509 below.)
EL509
These disposable, radiotranslucent dry electrodes have no shelf-life limitation and are ideal for
EDA/GSR applications. Use with LEAD108 and electrode gel—GEL101 recommended for
EDA/GSR.
To add gel:
1. Fill back cavity (adhesive side) with gel.
2. Add a drop of gel to the sponge pad.
3. Place the sponge pad into the cavity.
4. Press firmly to clear air pockets.
Circular contact area diameter: 1 cm
Backing: 25 mm x 44 mm
MRI Use: MR Conditional
Condition:
Carbon-filled plastic snap will not interfere with imaging; tested 3T-9T.
EL508/509 Components: Substrate: Tape with medical grade adhesive, Label: Bi-Oriented
Polypropylene (BOPP) or Vinyl, Stud: 40% Carbon-filled ABS plastic,
Eyelet: 20% glass-filled ABS plastic coated with Ag/AgCi, Reticulated
foam: Polyester-polyurethane, Gel: 10% chloride-liquid gel (EL508)
