Neurocare-B portable EMG/EP system is a compact EMG/EP system which integrates an external 1CH/2CH/4CH amplifier and a new control unit to do EMG, NCV, EP examination, it's convenient to be applied to some special environment such as ward, operating room, NICU and bedside examination with an ultra smart portable suitcase.

Features
1. Transmission and Anti-interference:
Fiber optical transmission between pre-amplifier and core unit ensure strong anti-interference capability, it also guarantee stable and reliable signal transmission with strong anti-interference capability.
2. USB 2.0 interface:
It's able mount with laptop or desktop, realize high-speed and secure data transmission.
3. Modular design:
Enables different combinations for different examination. It's convenient for transportation and maintenance.
4. Multi-lingual software and can be updated for free lifelong
Realize language conversion easily and can support convenient application in different language environment.
5. Humanization and strong capability of upgrade
Available ability to upgrade: 8/16 introperative monitor, suface EMG function and ASSR function.
