Digital EEG Equipment, Brand Name : Jiahua

We are offering trolley type digital eeg equipment.
features:
* adopting large scale integrated circuit (lsi) and improved anti-jam capability.
* doubly isolated the power supply and brain electrical signal to prevent creepage and to insure security.
* record 16 leads eeg without pencils.
* two ecg leads and one breathing lead for option.
* function of various event description such as open or close eyes, deep breathing and flash stimulation.
* arbitrarily set lead modes such as monopole, dual-pole and reference electrode.
* choose any lead to enlarge and automatically measure eeg waveform.
* auto-replay eeg wave and real-time compressed chart-array map.
* arbitrarily choose histogram, graph, and graph and percentage map.
* continuously replay spike wave relief map and dynamic 3d rotated relief map.
* arbitrarily set digital filtering, formfeed speed, gain, transmission bands and time constant settings.
* self-contained medical record management system and manifold report pattern.
