Specialized infusion apparatus:0.1ml/h-1000ml/h;
Ordinary infusion apparatus:0.1ml/h-600ml/h;
Remarks: with 0.1-30ml/h (0.1ml/h/step ); over 30ml/( 1ml/step).
Infusion accuracy error
Specialized infusion apparatus:±5% (medium speed, 23ºC, humidity: 60%).
Ordinary infusion apparatus:±10%(medium speed, 23ºC, humidity: 60%).
Total infusion volume preset: 0.1-9999ml. 
 Remarks: with 0.1-30ml/h (0.1ml/h/step ); over 30ml/( 1ml/step).
Occlusion sensitivity: It has three adjustable levels of occlusion pressure as high, medium and low.
Note: when the infusion pipeline is pressed, the machine will not occur alarm immediately, but detect pipeline wall pressure, so time of alarm is related with the position of oppressed pipeline. Below is medium sensitivity audible and visual alarm time (the smaller value is measured at outlet of pump with occlusion by purpose, the bigger value is measured about 1 meter from the pressure sensor with occlusion by purpose).
Low speed(1ml/h):250~500 seconds;
Medium speed (120ml/h):7~14 seconds;
High speed(600ml/h):0.2~1 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  50Hz. 
D C: 12V(built-in battery).
Fuse: F0.75AL, T1A (switching power supply L.N).
Built-in battery work time:
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. 
Amount of pills:
 When the equipment running 120ml/h and reach the minimum block alarm the amount of pills is 0.3ml, it reach maximum block alarm the amount of pills is 0.5ml.
working condition:
Environmental temperature:+5ºC-+40ºC; 
Relative humidity::20%-90%;
Product dimension and weight: 165×115×205(mm), 2.5kg.
Parameter save: when the system power off it can automatically save setting value at least five years( infusion volume and infusion speed will not be saved).
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. 
The equipment waterproofing grade: IPX1.
