Portable EMG/EP
Model: BoxEMG

BoxEMG Portable EMG/EP is the integrated multifunction diagnostic machine that can achieve Electromyogram (EMG) and Evoked Potential (EP) test. Based on the demand of clinical neurophysiologists, BoxEMG is optimized by combining a variety of product characteristic, humanized design and built-in USB data transmission. High anti-jamming capability is assured through the advanced technology of double optical fiber isolation and embedded direct current amplification. Modular design and specific application software using Windows XP makes the equipment easy to use and upgrade. Undoubtedly, BoxEMG is the best choice for the professional EMG/EP detection.

BoxEMG will lead you to a new mobile office at any time, and let you enjoy the freedom and convenience.
