NAME Digital Three Channels ECG
STYLE NO RSD903
DESCRIPTIONS ●Digital There Channel ECG Machine;
●Simultaneous 12 leads acquisition;
●Multiple operation mode (Manual /Auto);
●Self-test upon powering on;
●Designed with a high-resolution thermal printer to
print out ECG waveform, annotation as well related parameters for diagnosis reference;
●Digital isolation technology is adopted to minimize time/temperature drift of components so as promote adaptability of the unit to circumstance;
●Digital filter for effective inhabitation of baseline drift, interference, as well automatic position of baseline;
●Function of rhythem lead for observing abnormal ECG waveform and heart rate;
●Automatic measurement and interpretation of ECG waveform to relieve doctors from strain;
●Multiple print formats include 3-channel, 2-channel, 1-channel and particularly the one that combines 3- channel (for lead 1-aVF) and 2-channel (for V1-V6);
●AC/Rechargeable battery for supporting continuous examination when AC power supply is unavailable;
●For battery operation, ECG-903 is equipped with a charger and system for battery capacity management and protection itself from excessive discharge;
●Safety level corresponds to Class I, Type CF.
