BASE
Electrode cap BASE is a universal kit of removable Ag/AgCl sintered MCScap‑E electrodes with DB‑25MDB‑37M common connector and MCScap® textile cap with fixing rings. The electrode cap is designed for use with electroencephalographs and biological signal amplifiers.
Electrode cap BASE can be used for general EEG practice.
Textile cap is made of elastic material, preserving the shape and size. The cap provides the exact position of the electrodes on the head without additional measurements and adjustments. Large holes are provided for ventilation and access to the electrodes and patient’s skin.The cap is fixed on the head with the chin or chest belt. The caps are marked according to the 10-10 system. Size identification is carried out by the color of the seam.
MCScap‑E is a point Ag/AgCl sintered electrode for EEG recording. MCScap‑E is designed for research that requires frequent installation and quick removal of electrodes for cleaning and disinfection. Used with MCScap textile caps with retaining rings. The Ag / AgCl sintered electrode material guarantees minimum polarization and long-term signal stability, as well as an increased electrode life.
