EEG electrodes

Ag/AgCl electrodes for non-invasive recording of EEG and tDCs/tACs, ear electrodes and clamps, repair kits

OVERVIEW

Reusable passive electrodes MCScap are based on high-quality Ag/AgCl and Ag/AgCl sintered sensors which guarantee:

a high quality signal,
a long-term stable electrical contact,
a low noise reference electrode,

a minimum electrode polarization,
an excellent low frequency response.

All MCScap electrodes can be integrated into textile cap MCScap. Electrodes can have TouchProof connectors or can be preinstalled in the Electrode cap with common connector. All electrodes have special holes for conductive gel.
