Important Quality Control
* Brand new ABS engineering plastic mold injection molding.
* The 7-inch color LCD liquid crystal display shows waveform, menu (paper speed, gain, filter status, etc.), patient information (ID number, name, gender, age), and working status. The brightness of the LCD display screen can be adjusted to 1-8 levels, suitable for use in various lighting conditions.
* Adopting aluminum-magnesium alloy bracket, stable and reliable, with good shock resistance and easy to move.
* High-quality silicone full keyboard keys with a long lifespan and good tactile feel. Supports full keyboard patient information and hospital name input in both Chinese and English, with quick switching between uppercase and lowercase.
* Dual-use AC/DC power supply, built-in rechargeable lithium battery.
* Built-in USB interface, supports direct insertion of USB flash drive to copy data; can convert ECG data into images in batches and upload them to USB flash drive for viewing and printing directly by connecting to a computer and printer.
* Retractable handle design, comfortable to hold and easy to store.

Function
* The operation interface is available in both Chinese and English. The display can be set to show 3/6/12 leads simultaneously, and the grid and waveform size can be adjusted on the screen for easy observation by medical staff. The device can record 1 lead, 1+ rhythm, 3 leads, 6 leads, and 12 leads in both manual and automatic modes.
* The baseline width can be adjusted from level 1 to 4, allowing for the creation of neat and beautiful ECG waveforms according to personal preference.
* High-resolution thermal array printing, with adjustable print density of 1-10 levels, producing realistic and delicate waveform and character effects. Suitable for capturing ECG waveforms of adults, children, and newborns.
Baseline stability detection ensures that neat and beautiful ECG waveforms are printed every time.
Prints on 215mm thermal paper, with clear and accurate records of uncompressed ECG waveforms of three, six, and twelve leads, lead labels, sensitivity, paper speed, filter settings, analysis reports, and other information, which can be used for clinical diagnosis and research.
