Portable Digital Hospital Electrocardiograph 3 Channel Interpretive ECG  Machine ECG3A

Features:

1. The digital isolation technology is used to suppress the drift of ECG signal, AC filter, EMG filter and heart rate detection by the processor to ensure the authenticity and reliability of the output signal.
2. It has the function of automatic measurement of conventional ECG parameters (more than 200 cases), which can reduce the burden of doctors. Automatic mode and manual mode are available.
3. Baseline stability test, ensure that each time can be printed out neat and beautiful ECG waveform
4. Manual/auto 1, 1+1, 3CH display
5. Manual/auto working modes
