PermeH2 is an instrument for testing the Hydrogen gas permeability through plastic films, monolayer or multilayer barrier films, metallised or with surface coating, laminated or coextruded used especially for electronics, battery, PEM, polymer membranes and hydrogen transport. 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 .pdf 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. The system is safe, the hydrogen gas before being reintroduced into the environment is premixed with nitrogen in order to eliminate possible risks of fire and explosion, the software completely manages all phases and controls flow rates, concentrations and all parameters in order to guarantee a practical, reliable and safe measurement.
