The innovative Contura S400 Seal Tester offers manufacturers of food packaging machines and the food industry, in general, a unique solution for seal inspection in MAP (modified atmosphere packaging) and other packages in accordance with DIN EN 1779 and in close resemblence to ASTM F2338-09. Unless other solutions it can detect gross leaks as well as fine leaks which are undetectable by the naked eye or by the water bath method (also known as "bubble test").  The unique technology of Contura S400 can detect any leak (not only seal damage) without the need for tracer gas and at the same time without damage to the package.

Operating this seal tester is also simple and accurate. The flexible chamber consists of two highly elastic polymer membranes. By creating a vacuum, these membranes tightly enclose the tested package. The seal tester analyzes the pressure increase in a few seconds. Contura S400 Seal Tester can then detect even the smallest leaks rapidly and reliably.
