ecg machine Features

Output system: High-resolution thermal-array (8 dots/mm), it need not be adjusted. Re-cording frequency Response:150Hz (-3db, +0.4dB).

The device can record exact single ECG waveform and remark. The remark includes: lead sign, sensitivity, paper speed, filter state.

Under automatic mode, just press the button once, it starts record procedure, which can en-hance your work efficiency.

The language of operation interface include 

Chinese, English, French, Italian, Turkish, Spanish

The keyboard’s control is whole touch type, it’s convenient to operate.

LCD can display the operation state, which is convenient and readable.

Classification: class: I, CF applied part.

power supply: AC/DC, Rechargeable lithium battery inside.

This instrument can record 150 pieces of ECG waveform and print 90 minutes continually under the best DC state.

The figure of whole device is elegance and gliding.

According to dependency degree of deleterious fluid, this device belongs to common device.

According to the safe degree used under the condition with flammable anaesthesia gas mixed with air (or oxygen, nitrous oxide), this device belongs to the device which can’t be used under the condition with flammable anaesthesia gas mixed with air (or oxygen, nitrous oxide).

Digital signal processor for effective inhibition of AC, EMG and DFT, receive the better ECG waveform.

According the working mode class, this device is nit suit to continuous work state
