Water water everywhere
Water vapour is everywhere and creates more problems than almost everything else put together
Yet it is also useful when, as superheated steam it sterilises and purifies Sometimes it is essential that vapour can flow through a material for example the packaging on a sterile syringe or bandage, sometimes it must be barred as it degrades drugs (especially in powder form)

Vapour measurements faster than gravimetry
Meter can measure the water vapour permeability and transition rates of most materials and containers in as little as 30 minutes
The solution is a comprehensive vapour permeability laboratory testing service (and /or equipment), says Versaperm - which claims to be a leade in this complex field.
Versaperm's service is based on its own advanced design of WVTR (Water Vapour Transmission) meter, which can quickly produce results that are accurate to better than one part per million.
The meter is around 100 times quicker, and more accurate than conventional gravimetric techniques.
It can be used on huge range of medical, laboratory and QC materials or enclosures from foil laminates to inhalers and from paper or plastic packaging through to container seals and technical instruments.
It can also provide measurements of substances that might otherwise be decomposed by normal water content measuring techniques.
Sensitivities are in the range 0.05-3200g/m2/day.
