lost by unexpected results
But the engineering is easy to improve
Water vapour is extraordinarily
invasive and the wastage it causes cost UK businesses hundreds of millions
of pounds each year. Electronics deteriorating, components rusting, products
rotting, and pharmaceuticals failing – can all be caused because
the O rings, seals and enclosures that keep water out, don’t keep
our water vapour.
Many seals are virtually useless
when it comes to water vapour – which can pass through them virtually
unhindered to cause havoc within. Water vapour is omnipresent and insidious.
It causes biodegradation, chemical reactions, physical change and short
circuits. It often reacts in a counter-intuitive way by comparison to
Versaperm Limited, 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, seals, packaging, films,
coating or container.
The Versaperm WVTR (Water Vapour
Transmission) meter can cope with several samples at a time - often give
a reading in as little as 30 minutes – whereas the conventional
gravimetric measurement technique takes several days and is significantly
The meter is easy to use and
gives a series of digital readouts that can be recorded or simply read
off the LCD screen. It needs no re-calibration and requires, at most,
minimal training to give results that are accurate to better than one
part per million (with some samples accurate to a few parts per hundred
million). Sensitivities are in the range 0.05 – 3200g/m2/day.
The Versaperm system can not
only supply the equipment but also offers a testing service for a huge
range of products and packages – from O rings to sealants and even
from missiles to pizzas.
