Soil moisture sensor TDT

electrical conductivity

Buried sensors We use buried soil sensors because they provide the most realistic measurement of actual soil conditions. Drill-and-drop probes might be easier to install, but if you can not trust the measurement, what good are they? TDT Technology TDT technology is along with TDR the only sensor technology that provides trustworthy measurements for irrigation scheduling. Most other solutions rely on capacitive sensors that have proven unfit for this purpose. Approved by science We have dug into the research, so you don't have to. We only claim what the research supports. If you are considering an alternative solution, we will gladly help you compare it to ours based on scientific literature Measure the right thingOur buried sensors provide the most correct measurement of the soil because they do not disturb water flow after installation. Sensors of the probe design provoke what is called preferential flow where water from rain and irrigation is prone to travel along the surface of the stick, leading to misleadingly high measurements.
