Meter measures water vapour transmission
Water vapour is extraordinarily invasive, and the wastage it causes costs UK businesses hundreds of millions of pounds each year, according to Versaperm.
Water vapour is extraordinarily invasive and the wastage it causes costs UK businesses hundreds of millions of pounds each year, according to Versaperm Deteriorating electronics, rusting components, rotting products and failing pharmaceuticals can all be caused because the O-rings, seals and enclosures that keep water out, don't keep our water vapour

Seals and gaskets put to the test
The Versaperm WVT water vapour transmission meter can cope with several samples at a time, often give a reading in as little as 30min.
Meter puts seals to the test
The Versaperm WVTR (water vapour transmission) meter offers a quick and simple way to test materials, seals and finished enclosures.
Meter can help prevent water vapour damage
Water vapour meter has automated computer control that can cope with several samples at a time, and still give a reading in 30min for some materials.
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 compared with liquid water.
Versaperm has now introduced a quick and simple way to test all-important water vapour permeability and transmission rates for most types of enclosures, seals, packaging, films, coatings and containers.
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 conventional gravimetric measurement technique takes several days and is significantly less accurate, claimed the company.
The meter gives a series of digital readouts that can be recorded or read off the LCD screen.
It needs no recalibration and requires 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 0.053200g per square metre per day.
The Versaperm system also offers a testing service for products and packages from O-rings to sealants and even from missiles to pizzas.
