Features:
Digital isolation technology is for minimizing component drift v/s time& temperature to guarantee high-adaptability of the equipment to the environment.

Digital signal processor for effective inhibition of baseline drift, AC interference filter, EMG interference filter and the heart rate, to guarantee the authenticity and dependability.

Auto-regulation of baseline drift can effectively inhibit baseline drift, optimizing the printing position to achieve high-quality ECG.

With a high–resolution thermal printer to print out ECG waveform, describing the trace clear and accurate, annotation as well as related parameters for diagnostic reference.

Roll recording paper for ECG-203 is 63mm in width, simultaneous 12 lead acquisition, and 3 lead live record, high affectivity of ECG examination, good effect and economic utility.

Function of rhythm lead for observing abnormal ECG trace & heart rate.

Supported by AC/Rechargeable battery for continuous examination whenever is necessary. For battery operation, ECG-203 is equipped with a battery charger and a system for battery capacity management and protection.

Safety level for ECG-203 corresponds to Type CF, Class I according to the GB9706.1-1995 criterion.
