PROFESSIONAL-NT
Electrode cap PROFESSIONAL‑NT is the textile cap with pre-installed Ag/AgCl sintered MCScap‑NT electrodes with DB‑25M common connector. Electrode cap PROFESSIONAL‑NT is recommended for routine EEG, research EEG, hight-resolution EEG*.
(*optional)
The electrode cap is designed for use with electroencephalographs and biological signal amplifiers.
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 material or by the color of the seam.
MCScap‑NT is a cup Ag / AgCl sintered electrode for EEG recording. MCScap‑NT is designed for research requiring increased patient comfort for a long time. The Ag / AgCl sintered electrode material guarantees minimum polarization and long-term signal stability, as well as an increased electrode life. The conductive surface of the MCScap electrodes is not in direct contact with the skin. Contact is provided by a conductive substance. A hole in the electrodes is provided to add a conductive gel. Electrode have additional labeling what makes easy to rearrange them to new textile base.
Location of the output of the electrode cable from the cap (the point where the individual electrode leads are assembled into a common patient cable) is placed on the top of the head for comfortable EEG recording in the lying position.
