The ALPS RS Linear moving head leak tester uses an innovative, patented approach to inspect containers through the use of a continuous-motion, no-tooling machine. The system works on demand, monitoring the customer conveyor speed, sensing incoming containers and moving the test probe in sync with the movement of the bottle. This approach is ideal for hard-to-handle container designs. Typical speeds range from 10 CPM up to the 160 CPM range for the smallest containers.
