3-channel electrocardiograph SonoScape IE3

Features:

• It features digital isolation technology to minimise the impact of temperature and weather changes and thus ensure compatibility of equipment with the environment.
• The digital signal processing ensures the validity and reliability of the signal through the filtration of the alternating current, the myoelectric filtration and heart rate monitoring.
• It features an automatic adjustment of the baseline to minimise changes caused by interference and optimise printing position. Thus, it allows a high quality ECG.
• It offers automatic analysis and measurement of routine parameters to lighten the workload of professionals.
• The ECG waves are recorded with the thermal printing method, so the layout is clear and precise allowing a good diagnostic.
• The simultaneous use of 12-lead and 63 mm thermal paper allow obtention of an electrocardiogram rapidly, making out of this equipment an efficient, effective and affordable one.
• You can select a rhythm lead to facilitate observation of abnormal heart rhythm.
• Auto change AC / DC, built-in rechargeable battery, charging circuit of the battery and control and protection system for batteries.
• Classified as Class I and CF type according to the standard  IEC 60601-1.
• Intuitive and friendly display.
