The James Aquaprobe™
break-through in modern moisture measurement technology. By utilizing
the latest microwave and microprocessor technology, the Aquaprobe™ can determine
moisture content of different types of soils and other fine aggregate.
the five prongs in the soil to be measured and review the percentage
moisture on display. A
special guide is supplied to assist the user with inserting the prongs
in particularly dense soil.
The Aquaprobe™ Microwave Soil Moisture Meter uses
a five prong sensor to
measure the complex dielectric constant of the material
by the outer four prongs. As the dielectric constant of
is four to eight times greater than most natural soil types, changes in
water content directly affect the sensor
output. This output is
then converted by the integrated
microprocessor and moisture content is displayed directly as a
percentage of dry weight. An
average of five to ten readings is normally taken in order to
ensure a valid reading, especially as water does not distribute itself
evenly for many types of materials.
The basic unit
comes pre-calibrated for Lean Clay, Silt, Sand (Ottawa Sand and SP
sand) and general type of Silty Sandy soil.
These soils represent the most commonly found types.
This makes the basic unit the economical choice when
evaluating soil moisture levels.
system includes equipment to create custom calibration curves for
different types of soil. The instrument can be
programmed with up to ten different materials by the user. For highest
accuracy, the unit should be programmed for the material being tested.
Simple to use Windows™ software is
provided for calibrating the unit to the various materials.
Finally, the Aquaprobe™
instrumentation unit can store over 150 readings. Storage is complete
with the time and date for future
reference. Data can be recalled via USB interface to a personal
computer running Windows™.
