Stevens Water Monitoring Systems, Inc. products

The Stevens Tempe Cell System can employ five different methods to eliminate the uncertainties from soil moisture measurements and achieve the highest level of accuracy. This system uses an enhanced gravimetric method to measure soil moisture to obtain the actual volumetric water content and develop a soil moisture calibration equation to validate and/or program into soil moisture sensors. In addition, the system’s outputted data can be used to develop a soil-specific calibration curve, and to develop an algorithm to determine the soil’s matric potential using the HydraProbe. The Stevens Tempe Cell is ideal for mesonets, climate reference networks, and soil monitoring stations.
