The Leak Testing Machine is used for off-line Non-Destructive Container Closure Integrity Testing. It performs the Leak Testing process on one Container at a time by means of a Testing Chamber under Vacuum or Pressure. On pressing the Cycle Start button the Leak Testing process is run. Whether the result is Conforming or Non Conforming, the HMI clearly displays the status on the screen. The Measurement System provides both a "gross" and a "fine" leak test detection range.
