Save hours of labour
VARIOS generates thermal dryout curves automatically, so you can
focus on other tasks. No manual process of getting the soil in and
out of the oven. No repeated manual weighing of the sample. It's
all taken care of for you, including data acquisition and
analysis.
Thermal conductivity-simplified
Constructing a thermal dryout curve is a painstaking process
with the potential for human error. Time and effort go into
acquiring and setting up the right components, plus you spend hours
mixing samples, taking measurements, and fitting the data into a
curve. What if you could have something more accurate, more
reliable-and more automated? You can. Introducing VARIOS.
Get more done with automation
Remove the tedium and the human error out of thermal dryout
curves with VARIOS. It automatically generates complete,
high-resolution dry down curves with less effort and less cost, so
you can focus on what you love.
Engineered for accuracy
VARIOS was specifically designed to create thousands of thermal
dryout curves for the 400 mile Suedlink underground cable
installation in Germany. So it's engineered to be accurate,
affordable, and low maintenance. It combines legendary TEMPOS and
HYPROP technology to measure thermal conductivity as a function of
soil water content. And it's easy. Just insert the needle into a
saturated soil sample, and put it on the balance. VARIOS
automatically makes hundreds of precision thermal conductivity
measurements while the water evaporates from the sample. The mean
water content is calculated based on a continuous recording of the
sample weight change. Powerful software does all the calculations,
visualization, and fitting automatically, reducing the possibility
of error.
Reliable and compliant all-in-one solution
The ASTM D5334 compliant VARIOS uses the transient line heat
source method. That means it's a reliable measurement with short
heating phases and low heating power. This reduces water movement
due to heating and convection and reduces the measurement time. It
automatically corrects for temperature drift, and heating power and
time can be optimized for specific materials or properties. Plus,
every dryout curve has hundreds of data points, so you get the
detailed information you need to make the right decisions. And
VARIOS is an all-in-one solution. It comes with everything you need
to make complete thermal dryout curves including cables,
installation tool, and software. There's nothing else like it on
the market.
