NORME: TotalPerm complies with the norms ASTM F2476
Perme is an instrument for testing the permeability through plastic films, monolayer or multilayer barrier films, metallised or with surface coating, laminated or coextruded used especially for food, beverage, pharmaceutical and electronics packaging applications.
Perme, as well as performing measurements of permeability through thin films, can be equipped with modular accessories to carry out measurements on packaging containers of various types such as bag-in-box, PET bottles and packages.
The software Perme ExtraSolution® allows the user to work with full autonomy after only a few hours of training.
The principal parameters such as temperature, relative humidity, conditioning time and automatic end of measurement, are requested at the start of the software and then it is all automatic.
Moreover it is possible to plan a list of measurements on the same sample at different test conditions that are going to be run automatically by the instrument. In this way any human action is reduced to the minimum and any possible errors eliminated.
The software stabilizes the parameters with high accuracy and precision over all the measurement.
Testing conditions (temperature, relative humidity, concentration, …) are shown both as numeric data and graphical representation and saved in an HTML file and in text file to allow the full compatibility with any other software.
All the gas flows are electronically controlled so that the instrument is immune to changes of pressure both in the gas line and atmospheric.
The single point closure system and the special design of the chamber eliminates the need of cutting the samples to be tested.
