A New Interpretation of Vacuum Attenuation Method for Leak Detection Dynamics

Shanghai Qiyi's vacuum decay leak detector includes a vacuum chamber, a vacuum pump, and a high-sensitivity differential pressure sensor.The chamber can be modified according to the packaging product being tested to minimize air around the packaging and obtain more accurate readings.

Our leak tester only needs to insert the packaging into the vacuum chamber and cover it to start.The system only requires basic utilities such as air and electricity to operate.After the test begins, use a vacuum pump to create a vacuum around the packaging and isolate it.Then, allow the pressure to decay towards atmospheric pressure.Users need to determine an acceptable leakage rate based on pressure readings in order to accurately determine PASS/FAIL
