Direct Pressure Leak Tester

    The fourth generation of WaFu Brothers

  • The fifth-generation differential pressure leak tester from Washington Brothers uses compressed air as the medium and accurately detects pressure changes through a high-sensitivity sensor to achieve non-destructive and efficient air tightness testing. Compared with traditional water testing methods, it has three core advantages: 1) higher detection accuracy (smaller air molecules, micron-level leaks can be identified); 2) faster detection speed (test completed in 3 seconds); 3) zero secondary pollution. It is widely used in sealing test scenarios with high cleanliness requirements such as automotive parts and medical devices, and is an ideal choice for quality control of modern intelligent production lines.
