  • Technical Article: Air Under Water (AUW) - Also known as the "Bubble Test" / Dye Penetrant Leak Test
    AUW, also referred to as the "bubble test," may be okay for medium and large leaks, but is poor for SPC and correlation to other leak test methods is almost impossible. AUW can be used to detect. Air Under Water (AUB) - Bubble Test and Immersion Leak Testing. Please Note: You are viewing
  • High Throughput Leak Detection
    Various methods have historically been used to check leaks in systems and components from bubble tests to rotameters and pressure loss detection. While these traditional methods have their place, they each have serious drawbacks in accuracy, throughput, and automation. High Throughput Leak

    of the test equipment available. The limited dynamic range of conventional helium leak detectors required that a secondary test procedure be developed to cover the large, or gross, leak range. Several methods have been tried, and the most commonly used procedure, referred to as the bubble test, involves
