Introduction
YH-100G is a kind of single channel electrocardiograph, which features in printing ECG waveform by thermal printing system, prompting for "Lead off" or "Lack of paper", multi-language interface, recording ECG waveform in AUTO/Manual mode, convenient to operate.
Function
1)Adopt digital signal processing technology and get high-quality ECG waveform via power frequency filter, baseline filter and EMG filter of ECG signal.
2)Adopt high-resolution thermal printing system(8 dot/mm), no need for any adjustments. Recording frequency: up to 150Hz.
3)Real-time and continuously record clear and accurate ECG waveform and annotation character(including lead mark, sensitivity,
paper speed and filter state, etc.).
4)In AUTO mode, finish recording by pressing the button once, which improves work efficiency.
5)Multi-language (Chinese, English, French, Italian, German, Spanish, Turkish, Russian and Kazakh) interface and report.
6)In optimal DC state, up to 7-hour standby time, continuous print up to 4-hour, record up to 150 pieces of ECG waveform.
