a world leader in water vapour permeability measurement, produces
a fast, accurate, versatile instrument for measuring water
vapour transmission rates. It is ideal for an enormous range
of industrial, pharmaceutical and retail products and processes.
Water vapour can, for example, cause product failure, slash
shelf-life and can even be diagnostic of compositional changes.
Water vapour is
omnipresent and highly invasive. It can cause cornflakes to
go soggy, medicines to expire early, plastic piping to lose
water, electronics to fail. It is one of the most widely needed
measurements on everything from missiles to 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 can be provided for testing samples
from the size of a 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
