Technical parameters: 

Infusion flow rate
Specialized infusion apparatus:0.1ml/h-1200ml/h;
Ordinary infusion apparatus:0.1ml/h-600ml/h; 
Remarks: with 0.1-30ml/h (0.1ml/step); over 30ml/(1ml/step).
Infusion accuracy error
Specialized infusion apparatus:±5%(medium speed, 23ºC, humidity: 60%);
Specialized infusion apparatus:±5%(medium speed, 23ºC, humidity: 60%);
Total infusion volume preset: 0.1-9999ml.
Remarks: with 0.1-30ml/h (0.1ml/step); over 30ml/(1ml/step).
Occlusion sensitivity: It has three adjustable levels of occlusion pressure as high, medium and low.
Low speed(1ml/h):250~500 seconds;
Medium speed (120ml/h):7~14 seconds;
Above data is measured at the status of 25ºC ambient temperature, ordinary pressure, use ordinary PVC(∮3)infusion apparatus and high sensitivity.
KV0: 1-2ml/h.
Power supply:
A C: 220V±22V; 50Hz±1Hz;
D C: 12V (built-in battery).
Fuse: F0.75AL(socket back), T1A (switching power supply L.N).
Power consumption: 30VA.
Built-in battery work time: 30VA.
Under the sufficient battery, medium speed flow rate, the battery can continuous work about 2 hours after power is switched off. Run time is related to flow rate. Within the battery normal life, the run time should not be less than 2 hours. The battery could charge and discharge about 400 times. 
working condition:
Environmental temperature:+5ºC-+40ºC; 
Relative humidity: 20%-90%;
Product dimension and weight:185×115×196(mm), 3.8kg. 
security classification:
The equipment is conform to IEC60601-1-2 standard and can resist a certain electromagnetic interference, which is no electromagnetic interference to other devices. However, please keep the infusion pump away from strong electromagnetic equipment, for example: radio knife, MRI.
