The Emhart Inex MLP Plus provides a better alternative to older sampling pressure testing systems. Besides meeting the industry-accepted ASTM C-147 standard for internal pressure testing of glass containers, the MLP can also be equipped with an optional capacity measurement gauge, which the author believes is not available on any other sampling pressure testing system. The capacity measurement gauge is also available as an upgrade to existing MLP systems. Advantages of the MLP are: The system can test two different containers, as long as both have the same finish size; Job change parts are minimal; The system includes built-in pressure curve analysis that significantly improves the reliability of pressure test data; Because the MLP is computer-based, new features or upgrades can be made in software over the life of the system.
