Water vapour causes electronics to fail
The Versaperm WVT (water vapour transmission) meter can cope with several samples at a time - often giving a reading in as little as 30 minutes.
Water vapour is extraordinarily invasive and the wastage it causes cost UK businesses hundreds of millions of pounds each year Electronic failure, connection degradation, component rusting, and mechanical failures can all be caused by the simple misunderstanding that electronic enclosures designed to keep water out, also keep water vapour out

Very often they don't.
Many seals and enclosures are virtually useless when it comes to vapour which can pass through them virtually unhindered to cause havoc within.
Water vapour is omnipresent and insidious - unfortunately it can act in a counterintuitive way in comparison to liquid water.
Versaperm, a world leader in water vapour permeability measurement, has introduced a quick and simple way to test this all-important water vapour permeability and transmission rates for most types of enclosure, seal, coating and container.
The Versaperm WVT (water vapour transmission) meter can cope with several samples at a time - often giving a reading in as little as 30 minutes whereas the traditional gravimetric measurement technique takes several days and is significantly less accurate.
The meter is easy to use, it needs no recalibration and requires, at most, minimal training to give results that are accurate to better than 1ppm (with some samples accurate to a few parts per hundred million).
Sensitivities are in the range 0.05-3200g/m2/day.
Versaperm can not only supply the equipment but also offers a testing service for a huge range of products and packages from enclosures and O-rings through to microswitches and missiles.
