WECG400
The first parallel testing ECG tester specifically designed for wearable devices can simultaneously test ECG function on up to 4 devices with a single computer to accelerate testing time.
It provides compliance tests conforming with IEC 60601-2-47, YY0885, and YY 9706.247-2021, and can output 7 types of standard ECG waveforms to assist wearable devices in meeting regulatory requirements of accuracy.
