Differential Pressure Leak Tester

Overview Knowledge Standards Terms

The differential pressure leak detector identifies leaks by comparing the pressure difference between the test piece and a standard reference. The instrument pressurizes a sealed system; if a leak exists, the pressure drops, and the change is measured by a differential pressure sensor. It is used to test the sealing integrity of packaging, containers, and pipelines, ensuring leak-free products in industries such as food, pharmaceuticals, and electronics.

Selection

When selecting a differential pressure leak detector, it is important to consider a measurement range that matches the pressure of the test piece, ensure the accuracy meets inspection standards, and confirm the response time aligns with production rhythms. Check the instrument's stability and anti-interference capabilities, ensure the interface is compatible with the test system, and verify that it is easy to operate and maintain. Choose an explosion-proof or standard model based on the application environment, and refer to industry case studies to validate suitability.
