The PermTech PermeO2 is an instrument for testing the oxygen permeability (OTR) through plastic films, monolayer or multilayer barrier films, metallised or with surface coating, laminated or co-extruded used especially for food, beverage, pharmaceutical and electronics and packaging applications.
PermeO2, as well as measuring the permeability through thin films, can be equipped with modular accessories to carry out measurements on packaging containers of various types like bag-in-box, PET bottles and packages.
The software PermeO2 ExtraSolution® allows the user to work with full autonomy after only 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 all is fully automatic.
It is also possible to plan a list of measurements on the same sample at different conditions that are going to be run automatically by the instrument. In this way any human action is reduced to a minimum and any possible errors are avoided.
The software stabilises the parameters with high accuracy and precision over the complete measurement.
Testing conditions (temperature, relative humidity, concentration, …) are shown both as numeric data and graphical representation and saved in 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 eliminate the need of cutting the samples to be tested.
