Versaperm Vapour Permeability measurement


Water vapour permeability measurement equipment from Versaperm - ideal for adhesives, mastics and other sealing materials.

Versaperm Limited, a world leader in water vapour permeability measurement, produces a fast, accurate, versatile instrument for measuring water vapour transmission rates. It is ideal for adhesives, mastics and other sealing materials.

Water vapour is omnipresent and highly invasive and permeability is often a crucial test in an adhesive's or mastic's performance as it can seriously affect the properties of the combined product. It is one of the most widely needed measurements on everything from seals to laminates - and even pizzas!

The Versaperm WVTR (Water Vapour Transmission) meter can cope with several samples at a time and can give a reading in as little as 30 minutes - whereas the conventionally gravimetric measurement technique takes several days and is significantly less accurate

The WVTR meter is simple to use and gives a series of digital readouts that can be recorded or simply read off the LCD 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 wide range of chambers is available for testing samples the size of a section of thimble through to a 25 litre drum.

As well as vapour transmission, the equipment can be used to measure the Equilibrium Relative Humidity (ERH) of substances compounds that might otherwise be decomposed by normal water content measuring techniques.
