Everything gets wet on a boat! But not only is it important that things don’t leak, but also that no moisture finds its way inside critical equipment and electronics.

The problem is that many seals which keep out water as a liquid allow it to pass through virtually unhindered as vapour – possibly rendering a seal useless!  And there can be a lot of moisture about in a river or marine environment.  Versaperm Limited, a world leader in water vapour permeability measurement, has introduced a quick and simple way to test for this and thus help to overcome the difficulty.

The Versaperm WVTR (Water Vapour Transmission) meter was purpose designed for this task.  It can cope with several material samples, seals or enclosures at a time, often give a reading in as little as 30 minutes – whereas conventional gravimetric measurements take several days and are 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 in the parts per million range for most samples.
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 offers a water vapour permeability laboratory service for companies that need to test samples on an irregular basis.
