Negative pressure tester for infusion set

Technical Specifications:

1. Environment:

Working temperature: 5-40 ℃

Relative humidity: (45-80)%

Power supply voltage: 220V ± 22V

Grid frequency: 50HZ ± 1HZ

2. Technical parameters:

Negative pressure detection: -10 to -30KPa with an error not exceeding ± 0.5KPa, and LED digital display of negative pressure.

Negative pressure output -10~-30KPa ± 0.5KPa, LED digital display of negative pressure.

Measurement system negative pressure maintenance: It must not drift ± 0.5KPa within 1 minute.

Test duration: 60 seconds, with an error not exceeding ± 0.5KPa.

Usage:

Negative pressure tester for infusion setInhale not less than 25% of the nominal capacity of water into the infusion set, firmly install the tube on the negative pressure output of the testing instrument on the infusion set, connect the testing instrument to the power supply, turn on the power switch, wait for the negative pressure display to stabilize, then press the start button, and the testing instrument will automatically suck air. When the negative pressure display reaches -20 KPa, it will automatically stop sucking air and start timing for 60 seconds. During this period, after the pressure stabilizes, visually observe that there should be no bubbles in the infusion set (the negative pressure display should not exceed the original display value of 0.5KPa).
