The 10184 should be purchased when only one 12-cm rod on the CS620
(18591 orders two 12-cm rods) needs to be replaced. Water content is
averaged over the length of the rod. Therefore the reading from a probe
with 20-cm rods inserted vertically into the soil surface will be the
average value for the top 20 centimeters of soil. Probe rods may be
inserted at an angle to reduce the measurement depth.
Features
Rods for the HydroSense probe are available in 12- and 20-cm lengths.
There is no significant difference in performance between rod lengths.
The choice of length depends on the application.
