The system offered by INFICON includes the Contura S-series leak detector with integrated test chamber.
It works by placing the packaged product between two unique membranes that create a conformal vacuum chamber which is quickly evacuated. The gas flows through any package leaks into the chamber. Any gas collected inside the chamber causes an increase in pressure. The vacuum gauges then measure this change to calculate the package’s leak rate.
The leak test results are visualized on a display screen. When the test is completed, the chamber is evacuated and the system is ready for next test.
The Contura leak detector is gas independent, making it easy to integrate into any manufacturing environment and can be adapted to suit a manufacturer’s specific needs and acceptable leak rate range.
The instrument uses a proprietary differential pressure method to find leaks. This unique, non-destructive method allows dry food manufacturers to efficiently and accurately detect any leak - not only faulty seals - without the need for tracer gas and without damaging the package.
