ECG-912A (Twelve channels ECG machine)

Feature:

¨ Twelve channels digital ECG machine with interpretive.

¨ Designed with a high-resolution thermal printer to print out ECG,, waveform, annotation as well related parameters for diagnosis reference.

¨ Recording paper for ECG is 210mm in width.

¨ Digital isolation technology is adopted to minimize time/temperature drift of components so as to promote adaptability of the unit to circumstance.

¨ Digital filter for effective inhabitation of baseline drift, interference, as well automatic position of baseline.

¨ Self-test upon powering on.

¨ Function of rhythm 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 6-channel and 12-channel.

¨ AC/Rechargeable battery for continuous examination when AC power supply is unavailable. for battery operation, ECG-9012A is equipped with a charger and system for battery capacity management and protection itself from excessive discharge.

¨ For battery operation, ECG-912A is equipment with a charger & system for battery capacity management and protection itself from excessive discharge.

¨ Simultaneous 12 leads acquisition, 12-channel, 6-channel printing form at choice. date, time and parameters, including paper speed, heart rate, sensitivity, filter status and etc. print out.

¨ Visua display of operation menu, ECG waveform and parameters.

¨ Safety level for ECG-912A corresponds to Class I, Type CF.
