Versaperm has introduced its latest permeability meter, suitable for manometric testing of plastic film and sheeting.
This meter measures the vapour permeability of materials under variable conditions, and against a wide range of gases, including water and hydrocarbon-based vapours, O2, N and He.
It can measure permeability and diffusive flow across films, solid materials, seals, equipment and enclosures.
It can even take measurements through samples as thick as a wall.
Most materials, seals, tubes and products suffer from vapour diffusion, which leads to performance problems, resulting in anything from reducing the potency of drugs, through to shortened product shelf life and catastrophic electronic and equipment failure.
The Versaperm meter can determine vapour permeability for almost any material and gas, and can produce results in as little as 30 minutes.
Conventional gravimetric measurement takes days or even weeks.
The instrument is highly automated and provides reliable and reproducible results, with accuracy to a few parts per million, and in some samples a few parts per hundred million.
Versaperm also offers a permeability and diffusive flow testing service.
