ECG Machine 3 Channel (GTECG-2303G)
The ECG-2303G is a compact and reliable 3-channel electrocardiograph designed for fast and accurate acquisition, display, recording, storage, and analysis of ECG signals. It collects ECG signals from body-surface electrodes, processes them through filtering, amplification, and A/D conversion, and presents clear ECG waveforms to support clinical diagnosis. Intended for use by trained healthcare professionals, it is suitable for adult, adolescent, and pediatric patients across medical institutions, ambulances, first-aid scenarios, and physical examination centers.
