eWave data acquisition system



Educational System




Wireless , Light  and Low power


The eWave is a small and high-tech system for recording of EXG (EEG, ECG, EMG, EOG, ERP) signals.

The eWave amplifies bio signals by advanced and low noise amplifier and collects them by 2 to 128  channels of 24bit ADC 1K sample per second.

The DC coupled amplifiers record signals from 0Hz to 500Hz, including EEG, ECG, EMG, EOG and other DC signals.

The eWave transfers data to computer by Bluetooth wireless technology.

All of that combined with powerful eProbe software



eProbe offers all in one electrophysiology device for educational purposes.
