SUN-501 Syringe Pump's Advantages


1. Our syringe pump could use all brands through calibration (default setting is Terumo).
2. Auto-recognize the syringe size: 10, 20, 30, 50ml.
3. Wide flow rate range from 0.1-1600ml/h.
4. Available for adjust alarm volume (3 levels), occlusion pressure (3 levels).

5. Power Switching Function:When AC power is disconnected, automatically switch into battery power supply and give indication. When the AC power is connected, automatically 

switch into AC power working.

6. Repeat Alarm Function: If the alarm real reason is not be resolved within 1 minutes after press “SILENCE” button, it will give alarm again to remind to resolve the problem.

7. Battery Protection Alarm: For protect battery and safety infusion, the battery power will be displayed as different levels in sound and light from nearly finish to exhausted.

8. Double confirmation function when flow rate≥300ml/h, make safer and avoid misoperation.
9. The data can be cleared, make safer.
10. Lock the control panel during infusion, make safer.
11 For avoid misoperation, press “POWER” for 3 seconds to close the pump.
