ECG 903 Digital Three Channels Interpretive Electrocardiograph ( ECG Machine) Features: 1. Simultaneous 12 leads acquisition 2. Multiple operation mode ( Manual/ Auto/ European Mode) 3. Designed with a high-resolution thermal printer to print out ECG waveform, annotation as well related parameters for diagnosis reference. 4. Digital isolation technology is adopted to minimize time/ temperature drift of components so as promote adaptability of the unit to circumstance. 5. Digital filter for effective inhabitation of baseline drift, interference, as well automatic position of baseline. 6. Self-test upon powering on. 7. Function of rhythem lead for observing abnormal ECG waveform and heart rate. 8. Automatic measurement and interpretation of ECG waveform to relieve doctors from strain. 9. AC/ Rechargeable battery for supporting continuous examination when AC power supply is unavailable. ECG 912A Digital Twelve Channels Interpretive Electrocardiograph ( ECG Machine) Product Feature: 1.
