Complete Moisture Characteristics in 3-5 Days
HYPROP is a modular lab instrument that generates a moisture
characteristic curve and determines the unsaturated hydraulic
conductivity of soil samples in standard 250 ml soil sampling
rings. After setup the system generates the moisture characteristic
while running unattended.
Highly Accurate
Two precision mini-tensiometers measure water potential at
different levels within the sample while the sample rests on a
precision laboratory scale (2000 gram range; 0.01 gram resolution).
As the sample dries, changes in water potential are correlated to
changes in moisture content using the Wind/Schindler evaporation
method.
Verified Results
Results are verified and values for dry range and saturation are
calculated according to a selected model (i.e., van
Genuchten/Mualem, Bimodal van Genuchten/Mualem, or Brooks and
Corey.) Model parameters can be selected before, during, or after
the measurement procedure.
Advantages
- Easy and flexible handling
- Usage of intact standard sampling rings without
perforation
- Tensiometer shafts are installed into the sample from the
bottom side
- Low expenditure of time and costs
- Suitable for mobile applications
- High-quality results for the water retention curve especially
in the range close to saturation
- The hydraulic functions are consistently proved by numerous
readings
- T5x Tensiometers may measure beyond 250 kPa due to boiling
retardation
- The mathematical functions are profoundly adapted
- Simultaneous measurement of water retention curve and hydraulic
conductivity
- Suitable for all soils (provided Tensiometers can be
installed)
- No special requirements for the ambient conditions. Only the
evaporation conditions should remain more or less constant during a
measurement
- An existing scale with serial port can be connected to the
system
- Extendable to up to 20 assemblies for one scale
Limitations
- The measuring range is limited to the measuring range of the
Tensiometers
- Poor resolution of the hydraulic conductivity near saturation
(particularly in sandy soils)

HYPROP Balance
The balance is directly connected to the PC via an USB plug.
This offers you the possibillity to run multiple balances and
HYPROP-devices simultaniously. You profit from an outstanding gain
of time if you need to analyze a multitude of soil
samples. The great advantage of the balance is its unique
long-time stable "tuning-fork-principle". This pinciple is
excellent for the evaporationmeasurements of HYPROP.
The HYPROP-measuring head is directly connected to the scale and
offers a clearly defined attribution of balance and measuring head.
The HYPROP-FIT software detects the balance and the measuring head
autmatically and assigns weighing values to the tension. To reduce
weighing errors due to the cable, the new balance cable is much
thinner and more flexible
