<>Paper is one of the most widely used materials in the world and most of its handling, printability and quality characteristics are determined by its permeability to vapour, or its coating’s permeability. Measuring this essential property has now been made easier, faster and more accurate by a new instrument developed and produced by permeability experts Versaperm.

The novel uses and technical demands on paper have changed substantially over recent years. Marketers, printers, container manufacturers and other users demand ever more advanced performance. The new Versaperm MK VI WVTR has been produced in response to this need . It can accurately and consistently measure the permeability of a wide variety of materials such as papers and coatings - sometimes in as little as 30 minutes.

Conventionally gravimetric measurements take several days and give significantly less reliable results.

The Versaperm WVTR (Water Vapour Transmission) MK VI meters’ highly automated computerised control can cope with several samples at a time giving results that can be accurate to better than one part per million (with some samples a few parts per hundred million). Additionally the instrument can be configured to measure the diffusion rates of most gaseous elements (water, O2, CO2 etc).

Versaperm’s MK VI WVTR meter is accurate to better than a few parts per million, with some samples a few parts per hundred million. Sensitivities are in the range 0.05 – 3200g/m2/day.

A sample testing service is also available from the company - usually with a 24 hour turn around.
