Permeability leader Versaperm has launched a new version of its WVTR meter which can accurately measure the permeability of samples, materials, specimens, coatings, and enclosures for most gases. Labs increasingly have to measure an ever widening range of materials, compounds, laminates and components, due to the never-ending search for new characteristics.

The meter can measure to an accuracy of parts per million (per billion for some gases) and is around 100 times faster than conventional gravimetric techniques. It can be configured to measure the permeability of a wide range of gases, including Hydrogen, Helium, Hydrocarbons, Oxygen, Nitrogen and Carbon Dioxide.

Permeability affects properties ranging from the shelf life of pharmaceuticals and foodstuffs, through to the quality of print on a surface. The physics of some specimens often seems counter-intuitive – for example tightening a seal can actually make it leak more, and simple processes such as forming or bending can easily change permeability by 400%. This means the results for many products can not simply be estimated from an individual material’s properties but must be measured directly.

Versaperm’s new MK VI meter is highly automated and its computerised control and multiple chambers can cope with several samples at a time - and still produce a permeability measurement in as little as 30 minutes for some materials. It needs very little re-calibration and requires, at most, minimal training.
