Decagon SC-1 Steady State Porometer
Accurate, Affordable, Practical Stomatal
Conductance. The SC-1's breakthrough
steady-state technology makes accurate g
measurements affordable and practical for
everyday research.
No Moving Parts, most porometers
manipulate the environment around a leaf
using fans and dessicants. The SC-1 leaves
the environment alone, and instead
determines g by measuring the actual vapor
flux from the leaf through the stomates and
out to the environment.
Lightweight, Easy to Carry, weighs about half
a pound (300 g).

AccuPAR LP-80, Measure both PAR and LAI
The AccuPAR is a lightweight, portable PAR
sensor wand that lets you measure canopy PAR
interception at any location within a crop or
forest canopy. PAR data can be used with other
climate data to estimate biomass production
without destroying the crop. PAR is also
important in determining other canopy
processes, like radiation interception, energy
conversion, momentum, gas exchange,
precipitation
interception,
and
evapotranspiration.
The AccuPAR also uses radiation measurements
and other parameters to accurately calculate
leaf area index (LAI) non-destructively in real
time.
Infiltrometer & Drain Gauge
Infiltration Rates: for irrigation
design, classroom instruction,
erosion hazard evaluation, burn
severity studies …
Hydraulic Conductivity
Monitor groundwater leaching
Close your water balance
Measure Deep Percolation Accurately
The Drain Gauge G2 & G3 provides accurate
measurements of deep drainage and and
contaminant fluxes at a low cost.
Soil Water Content Sensors



Volumetric Water Content (VWC)
Measurements
Soil moisture is highly variable.
Accuracy from a single site isn't
enough to run an experiment. To
make good soil moisture
measurements, you need research
quality probes and you need a lot of
them.
Decagon's soil moisture sensors are
research grade probes at a price that
lets you completely characterize
your site.
Models
EC-5 Soil Moisture, small area of influence, Measures VWC only. Just
5 cm long with a 0.3 L measurement volume, this handy little sensor
is easy to install in the field and can also be used in nursery pots.
10HS Soil Moisture, large aea of influence, Measure VWC in a larger
soil sample. The 10HS has a 1 liter volume of influence
5TE Soil Moisture, Temperature and EC, Measures VWC,
temperature, and EC in soil. This three-pronged, 5cm long sensor
5TM Soil Moisture and Temperature, Get temperature data
integrated with your soil moisture data
WP4C
Fast, Accurate Ψ Measurements
Use the WP4C to measure Ψ in
5 to 10 minutes. Range: -0.1 to 300 MPa*
Versatile, The WP4C can be used
to measure the Ψ of any porous
material. It's typically used to
analyze soil, soilless substrate,
plant material, and seeds, but it
has been used to measure a
variety of unusual things,
including apples, bricks, oil, and
insect carapaces.
MPS-1, DIELECTRIC WATER POTENTIAL SENSOR
MPS-1 measures a wide range of soil
Ψ (-10 to -500 kPa -pF 2 to pF 3.71-)
without user maintenance and
factory calibration.
Best For:
•Deficit irrigation monitoring and
control
•Water potential monitoring in the
vadose zone
•Crop Stress
•Waste water drainage studies
•Plant water availability
KD2-Pro
The KD2 Pro is a fully portable field
and lab thermal properties analyzer.
It uses the transient line heat
source method to measure thermal
diffusivity, specific heat (heat
capacity), thermal conductivity, and
thermal resistivity.
Sophisticated data analysis is based
on 30+ years of research experience
on heat and mass transfer in soils
and other porous materials.
Regent Instruments Inc.
WinSCANOPY is a canopy structure (LAI, Openness, Gap fraction,
Clumping index, Gap Size Distribution) and solar radiation (Direct, Indirect,
Total Site factors, PPFD above/below canopy, Sunflecks) analyser system. It
is based on hemispherical images (acquired with a fish-eye or wide angle
lens) or narrow view angle images analysis. It can also do NDVI analysis for
plant canopy health/stress and Visible-FarRed quantification. As a
complete system it comes with a camera, fish-eye lens and accessories
(self-levelling mount, remote control and digital compass).
WinDENDRO is a semi-automatic image analysis system specifically
designed for annual tree-rings analysis. It can produce a few
measurements per ring (ring width, earlywood width, min, max and
average density...).
Regent Instruments Inc.
WinRHIZO is an image analysis system specifically designed for washed
root measurement in different forms. It can do morphology (length, area,
volume, ...), topology, architecture and color analysis.
WinRHIZO Tron and Tron MF are manual root measurement programs
that allows you to analyse images coming from minirhizotron underground
video or digital camera systems or scanned images of rhizoboxes.
WinSEEDLE automatically analyses seeds or needles much more
precisely than conventional camera or conveyor based area meters.
WinFOLIA is a Leaf Area Meter that is also a Leaf Morphology
Analyserand a Leaf Disease and Insect Damage Quantifier.
Regent Instruments Inc.
WinCELL is an image analysis system for wood cell anatomical structure
measurement. It can measure cell's walls and lumen (cell, vessel,
parenchyma) area, length, width, number, density, position and more on
images covering part of an annual ring or a few complete rings. It is an
alternative to wood density analysis done using x-rays.
WinCAM NDVI is a generic Color Area Meter that quantifies area occupied by
colors of interest (soil cover, disease quantification), classifies objects in function of color
(pass/fail, healthy/diseased), measures basic object’s morphology (area, length, width...),
do Color indexes and NDVI analysis (vegetation healthy/stressed) and can be used as a
color or grey levels profilometer (to analyse their variations along paths). It can be
calibrated to produce measurements in absolute reflectance values. WinCAM NDVI’s
applications are numerous. It is very sensitive and can detect and quantify very small color
differences.

Win Rhizo
WinRHIZO is an image analysis system
specifically designed for root
measurement in different forms. It can do
morphology (length, area, volume...),
topology, architecture and color analyses.
It is made of a computer program and
image acquisition components that can be
combined to meet different needs and
budgets.
WinRHIZO automatically or interactively
analyses washed roots.
For rhizotron or in-situ root analysis, see
our WinRHIZO Tron product.
Win Rhizo
The root diameter distribution graphic displays
the root length, area, volume or number of tips as
a function of root diameter or color. The number
and the width of the classes are user-definable
and can be changed at any time.
WinRHIZO displays the analysis over the image.
The color used to draw the root skeleton
indicates into which diameter class the part of
the root has been classified. The same color is
used for drawing the root distribution graphic
above the image.
Measurement data of the sample under analysis
is summarized on screen and is available in detail
in data files.
