The Watermark Sensor is a robust, user-friendly sensor, maintenance free, frost proof and buffered against varying salt contents of soil solution. The cable can be spliced up to a total length of 100m. However its reaction time to soil moisture variations is somewhat slower than tensiometer or volumetric sensors. Interpretation of data is easy, since measurement result is given in Centibar (soil water potential), valid for all soil types.

...as Profile Probe
for multible depths
Watermark Sensors are now also available as profile probe tor measuring multiple soil layers at only one spot, thus enabling the monitoring of soil water potential over a complete soil profile.
