In a marine environment it is obviously important to make compartments and electronics watertight.  The problem comes, however, when you try to keep out vapours such as water or hydrocarbon vapour as well.  Many materials that are an effective barrier to liquids, are nearly useless when it comes to vapours, which can create condensation.  So liquids get into watertight enclosures as a vapour - causing electronic failures and disasters when they do.

Versaperm Limited is a technology leader in vapour permeability measurement and has introduced a fast, simple and efficient way to check and measure this - not just for materials, but also for finished products and enclosures as well.  The system can, optionally, work for most gases including water vapour, hydrocarbons, hydrogen, oxygen, solvents, CO₂ and other vapours commonly found in the marine environment.

The Versaperm instrument was purpose designed for this task and gives results that are accurate in the parts per million range, (PPM) for most samples and vapours.  It can cope with several material samples, seals or enclosures at a time, often give a reading in as little as 30 minutes –conventional gravimetric measurements take several days and are significantly less accurate.

Versaperm also offers a water vapour permeability laboratory service for companies that only need to test samples on an irregular basis.
