3 channel Portable ECG Machine , ecg monitoring device rechargeable lithium battery
 
Features:

• 3.5" TFT Color LCD display shows the working status and ECG waveform.Check the waveform before printing to save record paper.
• 12 leads ECG simultaneous acquisition, digital signal processor, to get higher quality ECG waveforms through the AC filter, baseline filter and EMG filter of the ECG signals
• Simultaneous display of 3/6/12 leads ECG waveform, and the state of printing mode, sensitivity, speed, filter etc., to be easy for interpretation.
• Include multiform printing modes and format, such as auto 3*4 +1, auto 3*4,auto 2*6 +1, auto 2*6, auto 4*3, rhythm 4, rhythm 3, rhythm 2 and manual etc; the length of wave printing can be adjusted and the function of periodic printing is included to satisfy different applications.
