Seals, gaskets, O-rings, enclosures and mastics can be highly sensitive to changes in pressure, temperature and other conditions. Even worse is that many, while forming a good barrier to water, allow water vapour to pass straight through. Versaperm Limited, a world leader in water vapour permeability measurement, has introduced a quick and simple way to test the materials, the seals and the finished enclosures.

Water vapour is extraordinarily invasive and the problems it causes have been estimated to cost hundreds of millions of pounds in the UK each year. A simple programme of testing is often all that is needed to ensure that seals are effective – solving many of the problems that poor sealing can cause.

The Versaperm WVTR (Water Vapour Transmission) meter was designed for this task. It 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 less accurate.

The WVTR meter is easy to use and gives a series of digital readouts that can be recorded or simply read off a 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 a few parts per hundred million). Sensitivities are in the range 0.05 – 3200g/m2/day.

A wide range of variations is available, depending on the specific application, but both single and multi-sample systems and a variety of chambers are available for testing samples from the size of a thimble up to a pallet load and beyond.

As well as manufacturing the instruments, Versaperm also offers a water vapour permeability laboratory service for companies that need to test samples on an irregular basis.
