B-Alert X10 Wireless EEG System

B-Alert X24 EEG System

24 Channel Wireless EEG Headset

B-Alert X24 applies all sensors of the standard International 10-20 system simultaneously for efficient set-ups while also providing every subject a comfortable and individualized fit. Featuring the same high-quality signals as Stat X24 though labeled for non-medical applications, the system enables quantitative analysis techniques such as single-trial ERPs, LORETA/sLORETA, functional connectivity, and global brain assessments. All hardware is readily reusable with easy cleaning for repeated recordings in high throughput studies. From biomarker development to neurorehabilation, B-Alert X24 is enhanced by a suite of robust softwares to make this the most versatile wireless-EEG system available.

WARNING –The B-Alert wireless EEG systems are not intended for use in the diagnosis or treatment of patients. They are intended only for use in non-clinical research. For medical and clinical research EEG applications, please use the Stat X-Series Systems, which use the same EEG technology and provides labeling for prescription use in the home, healthcare facility, or clinical research environment to acquire, transmit, display and store physiological signals from patients ages 6 and older. The Stat X-Series system requires operation by a trained technician. The Stat X-Series System acquires, transmits, displays and stores electroencephalogram (EEG), electrooculogramn (EOG), electrocardiogram (ECG), and/or electromyogram (EMG), and accelerometer signals. The Stat X-Series System only acquires and displays physiological signals, no claims are being made for analysis of the acquired signals with respect to the accuracy, precision and reliability.
