Digital EEG System

Feature
PC-based EMG/EP measuring system
* Professional hardware technology. Its performance is credible and steady.
* Multi processing unit parallel dispose technology, which makes data collection and graphics display more rapid, it has 4 channels, which satisfies different work modals in the clinic EMG examination.
* Low noise, high CMRR, montage programmable electrode junction box.
* Independently programmable stimulators allows sophisticated examinations.
* Professional electromygram operation space, shortcut and steady.
* Intraoperative monitor capability.
* High speed and completely self-motion data collection and analysis, more nicety and more rapid with electrical stimulus, voice stimulus and light stimulus.
