Features

?Inner handhold designed for portability and Light Weight
?Designed with a high-resolution thermal printer to print out ECG waveform,
annotation as well related parameters for diagnosis reference.
?Roll recording paper is 63mm in width and 30m in length.
?Simultaneously acquisition of 12 lead ECG data, IEC Class, type CE safety
standard.
?Digital isolation technology is adopted to minimize time/temperature drift of
components so as to promote adaptability of  the unit to circumstance.
?Digital filter for effective inhibition of baseline drift, interference, as well
automatic position of baseline
?Self-test upon powering on.
?Function of rhythm lead for observing abnormal ECG waveform & heart rate,
Automatic measurement and interpretation of ECG waveform to relieve doctors
from strain.
?Multiple print formats include 3-channel, 2-channel, 1-channel, and particularly the one that combines 3-channel (for leadl-aVF) and 2-channel (for V1-V6).
?AC/Rechargeable battery for supporting continuous examination when AC power supply is unavailable.
?For battery operation, ECG-603 is equipped with a charger & system for
battery capacity  management and protection itself from excessive discharge.
