1.  Device Feature Description

1.  LCD large screen displays waveforms and 7 parameters in real time.

2.  Built-in host memory stores up to 30 waveforms and data sets.

3.  The probe tip features a freeze button for easy access to waveforms and data during measurement.

4. Bidirectional flow: Simultaneously reflects blood flow in both directions.

5. Capable of separately assessing the condition of arteries and veins.
