Meter sets the seal on reliability

Seals, pipes, joints, membranes, mastics, O-rings, cables and sheaths are excellent at keeping water and other fluids out.

Sadly water as vapour can often pass straight through them, and water is, by far, the world's most damaging contaminant.

Electronics can deteriorate, components rust, products rot - in fact cars, planes and even rockets have failed, simply because many materials don't keep water vapour out.

Versaperm has a new way to measure this permeability easily, quickly and accurately.

The new WVTR (water vapour transmission) MK VI meter gives results that can be accurate to better than 1ppm (with some samples a few parts per hundred million).

Results for some materials can be obtained in as little as 30 minutes whereas conventional gravimetric testing can take several days for a single measurement.

The meter's highly automated computerised control is easy to use, requiring at most minimal training even to cope with several samples at a time.

Sensitivities are typically in the range 0.05-3200g/m2 per day and the instrument can even be configured to measure the diffusion rates of most gaseous elements (water, O2, CO2, hydrocarbons etc).
