Product Detail

Product Tags

SM-3E is a kind of electrocardiograph, which is able to sample 12 leads ECG signals simultaneously and print out the ECG waveform with thermal printing system. Its functions are as follows: recording and displaying ECG waveform in auto/manual mode; measuring ECG waveform parameters automatically, and automatic analysis and diagnosis; pacing ECG detection; prompt for electrode-off and out of paper; optional interface languages (Chinese/English, etc.); built-in lithium battery, powered either by AC or DC; arbitrarily select the rhythm lead to conveniently observe abnormal heart rhythm; case database management, etc.


5-inch screen resolution color screen

12-lead simultaneous acquisition and 5-lead display

ECG Automatic measurement and interpretation function

Complete digital filters, resisting baseline drift, AC and EMG interference

Software upgrade via USB/SD card

Built-in rechargeable Li-ion battery
