Times change, technologies change, but the fundamentals of leak testing remain the same – the reliability and repeatability of your test results depend on how well you understand and compensate for testing variables.
The basics matter. They always have and always will. Sure, we now have technical capabilities, digital sensors, and control mechanisms that make it possible to measure, monitor, and tweak with far higher resolution and sensitivity than ever before. But these technologies should not be relied on to compensate for a poorly designed test equipment, or an uncontrolled variable like temperature.
