Description

Silver-silver chloride (Ag-AgCl) electrodes provide accurate and clear transmission of surface biopotentials. EL250 series reusable lead electrodes are suitable for most applications (ECG, EEG, EGG, EMG, EOG, and ERS recordings). For best signal performance use shielded electrodes (EL254S or EL258S) as recording electrodes and unshielded electrodes (EL254 or EL258) as ground or reference electrodes. Generally, for each Biopotential amplifier module, two EL254S or EL258S and one EL254 or EL258 are required.

EL250 series reusable electrodes are permanently connected to robust and pliable leadwires (1 mm OD). The leadwires terminate in standard Touchproof connectors. Unshielded electrodes terminate in a single Touchproof connector. Shielded electrodes terminate in two Touchproof connectors, one connects to the Ag-AgCl disk and the other connects to the leadwire shield. Use reusable electrodes with gel and adhesive collars or neoprene electrode cap with EEG placement labels (CAPMULTI-EEGCAP).

Use EL258 (8 mm recording diameter) for most applications
EL254S and EL258S are shielded electrodes; best used as recording electrodes
- BioNomadix units have no active drive circuit for shielded leads
EL258H features a 2 mm gel injection hole, useful for EEG monitoring; use as both recording and reference electrodes
Use EL254 (4 mm recording diameter) when closely spaced biopotentials are required
Use EL254-RT or EL258-RT for animal MRI setups; BIOPAC does not recommend using our MRI electrodes and leads with non-BIOPAC equipment.
