Stevens Water Introduces Innovative Matric Potential Sensor for Soil Water Measurement
The Stevens pF Sensor features high accuracy measurement in dry and saline soils and SDI-12 output for easy integration into new or existing soil monitoring systems.
PORTLAND, Ore., June 20, 2011 – Stevens Water Monitoring Systems, Inc., a leading supplier of soil measurement probes and environmental monitoring systems world-wide, is pleased to introduce the Stevens pF Sensor, an innovative soil sensor that measures the matric potential of soil while providing readings of higher accuracy than similar probes.
The Stevens pF Sensor measures the matric potential of the soil, which is also known as soil water potential. The matric potential of soil represents the force by which water is held within the soil, and how much energy is needed to overcome this force and extract water from the soil.
Using an innovative ceramic tip with internal heating element to measure the heat capacitance of surrounding soil, the Stevens pF Sensor provides extremely accurate measurement of the soil’s matric potential with readings that are stable even in dry or high-saline soils, and more reliable than other methods such as granular matrix probes or potentiometers.
Available now from Stevens Water Monitoring Systems, the Stevens pF Sensor is ideal for many applications, including plant and soil sciences, and can be used to determine plant-available water for crop growth. Featuring a standard SDI-12 output, the Stevens pF Sensor can be used in conjunction with other soil sensors such as the Stevens Hydra Probe II to provide an even greater analysis of sub-surface soil conditions.
