WATER FUSS
Water vapour permeability measurement equipment from Versaperm
- checking for anti-sogginess in the laboratory!
Versaperm Limited, a world leader in water vapour permeability measurement, produces a fast, accurate, versatile
instrument for measuring water vapour transmission rates and equilibrium relative humidity (ERH).
Water
vapour is omnipresent and, more often than not, degrades products and
results. Versaperm's equipment can test the permeability of a huge
range of materials and enclosures - from foil laminates to tubing and
from paint to packaging, paper and pizzas. It can also provide
measurements of substances that might otherwise be decomposed by normal
water content measuring techniques.
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 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.
