Grael 4K-EEG

An even more powerful evolution of the Grael EEG amplifier built for EEG studies for clinical and research applications including routine, LTM, ICU and Evoked potentials.

A DC-coupled, digital amplifier system with a high input range and 24-bit resolution providing amplification and digitization of electroencephalographic physiologic signals from surface,
cortical and depth electrodes. The amplifier provides 40 channels (32 isolated high-frequency referential channels, 8 bipolar channels), an integrated pulse-oximeter and event button input.

The unit has a POE 100BASE-TX network connection for both power and communication.

Product Features
