ECG300GA Portable 3 Channel Electrocardiograph
Professional-grade portable ECG machine with 12-lead signal collection, automatic waveform analysis, and thermal printing. Ideal for clinical settings, home visits, and body examinations with up to 8 hours of battery runtime.
Clinical overview
The ECG300GA is a portable 3-channel electrocardiograph designed for rapid, accurate cardiac assessment in clinical and field settings. It collects synchronised 12-lead ECG signals and employs advanced digital signal processing—including AC filtering, baseline correction, and EMG noise rejection—to deliver high-quality waveforms suitable for diagnostic interpretation.
The device features automatic ECG parameter measurement and diagnostic analysis, reducing clinician workload and enabling consistent interpretation across multiple examinations. With built-in case memory (expandable via SD card), bilingual interface, and flexible printing modes, the ECG300GA supports diverse clinical workflows from routine screening to detailed rhythm analysis.
