Water Vapour Permeation
With our water vapour permeability testers, the permeation amount of water vapour through a material layer can be measured. The specific ambient temperature and humidity can be set for each test procedure. Depending on the requirements, devices are available for flat packaging materials or finished packaging, as well as different sensors or measuring methods.
The devices for barrier materials WVTR-E1, -E2, C330 are equipped with an electrolytic sensor, the devices WVTR-I1, -I3 and W401, W405 with infrared sensors. These units have integrated software and can test both finished packages and flat material samples.
With the models WVTR-W1, -W3, -W6, -W6A and -W12, as well as W806/812 permeation is determined by weight measurement. The numbers at the end of the designation stand for the number of chambers. The model WVTR-W12 therefore has 12 measuring points.
