The Unseen Threat of
Water Vapour in Electronics

The Unseen Threat of water vapour in electronics

In the world of electronics, water vapour poses an unseen menace, infiltrating enclosures and components, wreaking havoc on everything from missiles to marine electronics. contrary to common belief, the problem isn't liquid water, even in harsh marine environments, but invisible water vapour. This insidious vapour can permeates through any material, condensing on the inside and causing electronics failure.

Versaperm’s MS Vapour Permeability meter is a cost-efficient a solution to this problem.

The severity of this is often underestimated. Materials like cellulose, EVOH, or PVOH may provide excellent barriers against liquids, yet they allow water vapour to flow almost unimpeded. Versaperm's equipment precisely measures the vapour permeability across various conditions, designs, and materials. This empowers manufacturers to choose or develop optimal materials and manufacturing techniques for each specific product, ensuring maximum protection against the silent threat of water vapour.

Beyond product optimization, the equipment can also provide an efficient quality control system, recognizing that material properties often vary significantly from batch to batch.

Versaperm's technology is fast, providing an easy and accurate way to measure vapour permeability not just for water vapour but also for hydrocarbon vapour and virtually all other gases, including hydrogen, oxygen, solvents, and CO2.

Results are accurate in the Parts Per Million (PPM) range for most materials, with some achieving even finer resolution. Multiple material samples, seals, or enclosures can be measured simultaneously, sometimes in as little as 30 minutes.

For companies requiring sporadic testing, Versaperm offers a vapour permeability laboratory service, ensuring access to cutting-edge solutions without the need for dedicated equipment.
