CONTROL DRAMATICALLY BOOST

Water vapour is
extraordinarily invasive and the food wastage it causes
has been estimated to cost hundreds of millions of pounds
a year. Packaging that uses suitable permeability
materials can substantially extend product life, prevent
products drying-out, over-hydrating, and considerably
reduce this waste.
Far and away
the most critical factor is water vapour and
vapour permeability experts Versaperm have introduced a
new generation of instrumentation to measure this for the
food and packaging industries.
The Versaperm WVTR (Water Vapour Transmission) MK VI
meters highly automated computerised control can
cope with several samples at a time - and still give a
reading in as little as 30 minutes for some materials.
The conventionally gravimetric measurement technique
takes several days and gives significantly less accurate
/ reproducible results.
The MK VI gives results that can be accurate to better
than one part per million (with some samples a few parts
per hundred million). Sensitivities are typically in the
range 0.05 - 3200g/m²/day.
As well as
vapour transmission, the equipment can be used to measure
the Equilibrium Relative Humidity (ERH) of foods.
Versaperm also operates a laboratory service for
companies where the volume or logistics of measurements
does not demand a dedicated instrument.
