NORME: MultiPerm complies with the norms DIN 53380-3, ASTM D3985, F2622, F1927, F1307, JIS K-7126, ISO 15105-2 for OTR measurements, with the norm ASTM F2476 for CO2TR measurements.

MultiPerm is the only instrument on the market, based on patented technology, that performs permeability measurements on two different kinds of gases. MultiPerm is offered with two sensors to be chosen by the customer either oxygen, carbon dioxide or water vapour. In this way MultiPerm has the ability to characterize the barrier properties of the film with two different gases testing exactly the same surface, avoiding the need of substituting the sample.
With this instrument it is possible to measure plastic films, monolayer or multilayer barrier films, metallised or with surface coating, laminated or coextruded, especially those used for food, beverage, pharmaceutical and electronics packaging applications.
MultiPerm, as well as performing tests of permeability through thin films, can be equipped with modular accessories to carry out measurements on packaging containers of various types such as bag-inbox, PET bottles and packages.
MultiPerm stands as the ideal solution for companies that produce or use barrier packaging and want the highest performance in a single instrument at competitive prices. The special software MultiPerm-ExtraSolution® guarantees maximum simplicity of operation.
You can plan a list of measurements on the same sample using different gases and conditions that are going to be run automatically by the software.
Choosing MultiPerm is the best choice that makes the life in the laboratory.
