ECG300G Three-Channel Electrocardiograph

The ECG300G Three-Channel Electrocardiograph can simultaneously collect 12-lead ECG signals and print waveforms via the thermal printing system. The device includes features such as recording and displaying ECG waveform in AUTO/Manual mode, prompts for “Lead off” and “Lack of paper,” a multi-language interface, AC/DC power supply, optional rhythm leads for observing abnormal heart rhythm, case database management, etc.

Sync collection for 12-lead ECG, adopt digital signal processing technology and get high-quality ECG waveform via power frequency filter, baseline filter, and EMG filter of ECG signal.
Displays 3/6/12-lead ECG, print mode, sensitivity, paper speed, and filter state, etc. on one screen
Multiple printing modes and formats, including manual, auto 4x3, auto 3x4+1, auto 3x4, auto 2x6+1, auto 2x6, auto 3-2+1, auto 3-2, auto 1x12+1, auto 1x12, rhythm 4, rhythm 3, rhythm 2, etc. Waveform length printed can be adjusted, and with the timed print function, which meets different requirements.
Built-in large capacity memory stores at least 1000 cases
Multi-language (Chinese, English, Spanish, Turkish, Polish, Italian, French, German, Portuguese, Russian, Ukrainian, Serbian, Vietnamese, Slovenian, Slovak, Bulgarian, and Nigerian language) interface and report.
