Introduction
This series of digital electrocardiographs supports synchronous 12-lead signal acquisition and comes with an integrated LCD display. Equipped with a high-performance processor and a high-resolution thermal printing system, it provides stable ECG recording and reliable performance. Featuring a well-organized control panel and a versatile function set for efficient routine examinations, it is ideal for hospitals, clinics, and primary care facilities. The unit can operate on AC mains power or its built-in rechargeable battery. It incorporates a protected charging circuit with overvoltage protection and undervoltage shutdown to ensure safe daily operation.
