Getting the measure of an invisible problem

Many materials are a good barrier against liquids, but when it comes to vapours, which are usually invisible, they are often very poor barriers. Versaperm's measurement system is fast and offers a simple, accurate way to measure vapour permeability, not just for water vapour but for hydrocarbon vapour and most other gases including hydrogen, oxygen, solvents and CO2.

Results are accurate in the parts per million range for most materials and enclosures and it is possible to characterise several separate material samples, seals or enclosures at one time – sometimes in just 30 minutes.

As well as manufacturing the instruments, Versaperm offers a permeability laboratory service for companies that need to test samples on an irregular basis.
