The OM-CP-SMR101A model has been discontinued. Please see the HSM50 series as a possible alternative or contact our Data Acquisition Engineering department.
The OM-CP-SMR101A is a small,
battery powered, soil moisture data
logger in a weatherproof enclosure.
It provides accurate volumetric
water content measurements over a
complete range from dry to saturated.
The OM-CP-SMR101A has a
10-year battery for long-term
deployments and soil studies, over
multiple seasons. It also features a
4 Hz reading rate, a multiple start/
stop function, ultra-high speed
download capability, 1,000,000
reading storage capacity, optional
memory wrap, battery life indicator,
optional password protection,
and more.
The OM-CP-SMR101A comes
with the OM-CP-SMRPROBE, a
high accuracy soil moisture probe
(pictured above), with a response
time of 10 ms, that can be used in all
soil types.
For easy soil moisture analysis and
trend information, our user friendly
software provides a time and date
stamped graph. This data may be
viewed, printed or exported to
third-party programs (Excel, etc) for
more detailed analysis and irrigation
management. Soil moisture data
is essential in determining and
scheduling irrigation for proper plant
growth, care and research. This
data is also useful in determining
the health of the soil and plant root
systems.
The storage medium is non-volatile
solid state memory, providing
maximum data security even if the
battery becomes discharged.
