EL500 SERIES DISPOSABLE ELECTRODES
EL504
EL508
EL509
The EL500 Series snap
electrodes provide the same
signal transmission as
BIOPAC’s reusable
electrodes, with added
convenience and hygiene.
Each peel-and-stick
electrode is pre-gelled and
designed for one use only.
Use disposable snap
electrodes with BIOPAC’s
SS2L electrode lead set.
EL510
Part Ag-AgCl Adhesive/Disposable Electrode Type
EL500
Paired electrodes: Use for general-purpose EMG measurements, nerve conduction measurements,
and cardiac output.
41mm spacing (center to center) on 4mm x 82mm x 1.5mm foam
EL501
Small stress test electrodes: Use for short-term recordings where the subject may be in motion or
when electrodes should be closely placed, as for multi-channel ECG, EGG, EMG or EOG.
38mm diameter mounted on 1.5mm thick foam with strong adhesive
EL502
Small pre-gelled electrodes Most appropriate for long-term biopotential measurement recording
sessions, these pre-gelled electrodes have a 10 mm contact area on a 41mm (dia) backing that
resists moisture. The electrodes include a hypoallergenic adhesive solid gel that adheres well to the
skin but leaves no residue when removed.
EL503
General-
purpose
electrode
Ag-AgCl Adhesive/Disposable Electrode, 35mm diameter vinyl tape, 10 mm contact area, gel.
These economical, pre-gelled electrodes are most suitable for short-term recordings. These
electrodes have a 10 mm contact area on a 41mm (dia) backing that allows close electrode
placement where necessary, with a slightly less firm adhesive for “ouchless” removal. The
electrodes incorporate hypoallergenic liquid gel and are high chloride for quick, accurate readings.
EL504
Cloth base, 2.5 cm square electrodes. Particularly useful for applications on non-conforming
surfaces, such as the face for EMG or fingers for nerve conduction studies.
The adhesive solid gel ensures good contact, and the silver-silver chloride (Ag-AgCl) electrodes
provide accurate and clear transmission of surface biopotentials. Use these comfortable and
conforming electrodes in EMG, nerve conduction, ECG, sleep studies, exercise physiology, etc.
The latex-free, hypoallergenic electrode adheres well and is repositionable and suitable for long
term use without irritation.
