EEG-Z3™ Sensor

EEG-Z3 is a pre-amplified electroencephalograph sensor with built in impedance checking and 3 modes of operation: regular EEG mode (2 Hz – 1 kHz), low frequency mode (0.01 Hz – 1 kHz) for evoked potentials and low frequency applications and DC mode (0 Hz – 1 kHz) for slow cortical potentials. Modes can be changed on-the-fly. Also includes DIN input connectors for use with standard EEG electrodes.
