1. Introduction
The
SoilVUE™10
is
a
time-domain
reflectometer-based,
soil-profile
probe
that
measures
volumetric
water
content,
permittivity,
electrical
conductivity,
and
temperature
at
multiple
depths.
This
probe
was
designed
with
environmental
researchers
and
environmental
monitoring
network
operators
in
mind,
and
is
ideal
for
long-term
outdoor
operation
and
for
applications
that
require
highly
accurate
measurements.
The
SoilVUE
10
has
two
probe
length
options.
The
0.5
m
option
makes
measurements
at
six
depths
(5,
10,
20,
30,
40,
and
50
cm),
and
the
1
m
option
makes
measurements
at
nine
depths
(5,
10,
20,
30,
40,
50,
60,
75,
and
100
cm).
Waveguides
(measurement
rods)
are
embedded
in
threads
and
are
centred
on
the
measurement
depths.
The
threaded
design
allows
it
to
screw
into
a
hole
created
by
a
standard
5-cm
(2-inch)
hand
auger.
This
simple
installation
procedure
reduces
cost,
complexity,
and
disturbance
of
the
soil.

2. Precautions
l
READ
AND
UNDERSTAND
the
section
at
the
front
of
this
manual.
l
Although the SoilVUE 10 is rugged, it should be handled as a precision instrument.
l
Depth of the hole that the SoilVUE 10 is installed in needs to match the SoilVUE 10 length.
Mark the installation tool to align with the length of the probe to ensure a proper depth is
obtained. Gaps between the bottom of the SoilVUE 10 and the bottom of the hole may
adversely affect the measurements.
l
Water should be used to wet the sides of the hole, reducing the force needed to install the
probe.
l
This is a robust sensor, but it is possible to break by applying excessive force during
installation.
l
Care should be taken to ensure the sides of the hole are even and do not become tapered
with repeated removal of soil.
l
To prevent damage to the connector pins, the plastic cap should be left on the cable
connection during installation.
