Compact and Portable Design
Battery-powered amplifier with USB connectivity integrates easily into hospitals, clinics, and research laboratories.
The Mitsar-EEG-201 is a compact, PC-controlled EEG amplifier system designed for dependable clinical EEG recording and advanced brain signal analysis. With support for up to 21 EEG channels, high input impedance, and low internal noise, it captures stable brain signals suitable for both clinical diagnostics and research applications.
Powered by internal batteries and connected through USB, the system integrates easily with a standard computer running dedicated EEG acquisition software. Clinicians can visualize EEG signals in real time and perform advanced analyses including digital filtering, spectral analysis, coherence measurements, and topographic brain mapping.
Compact and portable, the Mitsar-EEG-201 fits easily into any workspace. It supports routine EEG recording, event-related potential (ERP) studies, and a wide range of brain monitoring applications.
Built around a high-performance multichannel biosignal amplifier, the MITSAR-EEG-BT records electrical activity from the brain and converts it into high-resolution digital data for visualization, storage, and analysis on a computer. This integrated hardware and software platform provides a reliable solution for both routine EEG acquisition and advanced neurophysiological research.
The system supports 19 or 21 EEG channels depending on configuration, along with an auxiliary physiological channel. Its battery-powered design and USB connectivity allow it to integrate easily into clinical environments while remaining portable enough for mobile recording setups.
The included software provides a comprehensive set of EEG acquisition and analysis tools. Clinicians can apply digital filters, change montages, visualize signals in real time, and perform advanced analyses such as spectral and coherence measurements. The platform also supports event-related potential (ERP) recording and can be expanded with optional modules for video EEG and additional research capabilities.
Clinicians choose the MITSAR-EEG-BT for its combination of signal quality, simplicity, and portability. The amplifier's high input impedance, low internal noise, and strong common-mode rejection help produce stable recordings while minimizing electrical interference.
Its PC-based design streamlines EEG workflows. Data acquisition, visualization, and analysis are handled within a single software environment, allowing clinicians to focus on interpreting results rather than managing hardware.
The compact amplifier and battery-powered operation make the system easy to move between exam rooms or deploy in mobile testing environments. Combined with compatibility with standard EEG caps and electrodes, the MITSAR-EEG-BT adapts easily to a wide range of clinical and research protocols.
