The James Aquaprobe T-S-30 Soil
Moisture
MeterA microwave meter for rapid determination
of moisture content in different types of soils. 
The James Aquaprobe represents a
break-through in modern moisture measurement technology. By utilizing
the latest microwave and microprocessor technology, the Aquaprobe can
determine the moisture content of different types of
soils and other fine aggregate. Simply insert
the instrument in the container and fill the container with a sample of
soil to be measured. After shaking the
container a few times, the instrument will
instantaneously display the percentage of moisture
content on the easy to read display. The Aquaprobe Microwave
Soil moisture meter uses a five prong sensor to
measure the complex dielectric constant of the material
encompassed
by the outer four prongs. As the dielectric constant of
water
is four to eight times greater than most natural soil types, changes in
water content directly affect the sensor
output. An average of five to ten readings is normally taken in order to
ensure a valid reading. This output is then converted by the integrated
microprocessor and moisture content is displayed directly as a
percentage of dry weight. The unit comes
calibrated for Lean Clay, Silt, Sand (Ottawa
Sand and SP sand) and general type of Silty sand soil. It
can also 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 WIN95/WIN XP software is provided for
calibrating the unit to the various materials. Finally, the Aquaprobe can store
over 150 readings. Storage is complete with the time and date for future
reference. Data can be recalled via RS-232 interface to a personal
computer running WIN95/WINXP.
