hIight quality portable digital 12 channel 12 lead ECG machine

Hotsale Cheap Digital Hospital Electrocardiogram 12 Channel ECG Machine BM-ECG12A

Features:

1. It has the function of automatic measure of conventional ECG Parameters (more than 200 cases),which can reduce the burden of doctors. Automatic mode and manual mode are available.
2. Baseline stability test,ensure that each time can be printed out neat and beautiful ECG waveform.
3. 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.
4. Manual/auto 1, 1+1, 3, 6, 12CH display.
5. Manual/auto working modes.
