Versaperm Vapour Permeability measurement


£100Ms Wasted Every Year
Water vapour permeability - plastics and rubber leak!

The majority of plastics or rubber products are impervious to water - but many of them allow water vapour to pass straight through! This causes widespread waste – from drugs that lose potency, to food that decays and products that fail.

Water vapour behaves strangely – often counter-intuitively (the more tightly you screw some containers down, the more they leak). As a result accurate permeability measurements can be vital - the answer is the WVTR meter from Versaperm.

The meter is quick, easy and accurate, measuring to better than one part per million. It is ideal for a vast range of materials and containers. Conventional techniques take several days, but the Versaperm meter takes from as little as 30 minutes for many materials.

The meter can measure several samples at a time and the press of a button gives a series of digital readouts that can be recorded or simply read off the LCD screen. The equipment needs no re-calibration and requires, at most, minimal training. Sensitivities are in the range 0.05 – 3200g/m2/day.

A wide range of product options are available, depending on application. They include single and multi-sample systems plus a variety of chambers for testing samples the size of a thimble up to 25 litre bottle. Special options allow testing of products as big as pallet load and beyond. An overnight testing service is also available.
