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.
