ELECTRODES
In selecting the application site for any style of electrode, care should be taken that:
1)
Electrode site is dry and free of excessive hair.
2)
Electrode is not placed over scar tissue or on an area of established erythema or with a lesion of any kind.
3)
Skin is properly prepared. (Prepare the skin at the electrode site. Use the ELPAD to lightly abrade the skin
surface. Use a brisk dry rub to prepare the application site. Avoid excessive abrasion of the skin surface.)

EL654/658 SPECIFICATIONS
Sensor diameter: 4 mm Ag-AgCl (EL654,) 8 mm Ag-AgCl (EL658)
Housing diameter: 13 mm
Overall height: 6 mm (EL654,) 8 mm (EL658)
Gel cavity: 2 mm deep
Snap: 1 mm thick Ag-AgCl sintered sensor element mounted in an epoxy housing; all parts are firmly
encapsulated with epoxy, resulting in a tough, durable waterproof assembly
How to Clean Reusable Electrodes
1. Do not leave GEL in the cavity after use. If GEL is left in cavity, the Ag-AgCl electrode disk could degrade
quickly with time because the electrode surface is somewhat porous to promote good conductivity to the
GEL.
2. To clean the reusable electrode, use a cotton swab or toothbrush with tap water.
3. Use any lab cleaner with pumice (such as Ajax) with cotton swab or toothbrush to remove any dark
residue from electrode surface.
4. Use Hydrogen Peroxide solution (2-3%) to brighten electrode surface (optional) or to sterilize electrode.
Do not place the electrode in solution, but simply clean the electrode surface using a cotton swab.
5. Dry electrode off completely before storage.
