HydraProbeIt is a soil sensor with special technology and strong durability, capable of simultaneously and continuously accurately measuring three soil parameters: moisture content, conductivity, and temperature. As a designated sensor by the US Department of Agriculture, National Oceanic and Atmospheric Administration, and NASA，HydraProbeDeveloped by the Department of Physics at Dartmouth College, it is a sensor based on dielectric impedance, which is different from soil sensors based on capacitance or time-domain reflection,HydraProbeuse50MHzThe radio frequency fully characterizes the medium spectrum, separates the energy storage of soil dielectric constant (actual dielectric constant) and energy loss (imaginary dielectric constant), and then performs complex mathematical calculations through a built-in microprocessor to eliminate measurement errors caused by temperature and salinity. This technology not only enablesHydraProbeIt can provide high-precision soil water content, conductivity and temperature data, and greatly reduce the variability between different sensors without calibration.

Due to the conductivity of salt when mixed with water, soil conductivity can be used to approximate soil salinity. Nutrient accumulation, poor drainage, and saline irrigation can lead to unnecessary salt accumulation in the soil. When using a capacitive soil moisture sensor, an increase in soil salinity can affect the determination of soil moisture contentbe situated betweenThe Technology of Electrical ImpedanceHydraProbeSensors are not affected by salt.

main features

• Using dielectric impedance technology to measure moisture content, insensitive to temperature and salt content, ensuring data measurement accuracy;

• No calibration required, can continuously measure moisture content, conductivity, and temperature data for a long time;

• Adopting sturdy and durable stainless steel probes and sealed waterproof design, each sensor comes with a 5-year warranty；

• Can be applied to various soil types, including hard clay;

• useSDI-12Communication protocol，Compatible with any device withSDI-12Functional data collectors, such aseTracter, can connect up to simultaneously62A sensor;

• Easy to install and require minimal maintenance.

GroPoint Pro is a highly stable and accurate sensor that provides measurements of soil moisture, soil temperature, conductivity, and can also serve as a wet peak sensor, providing additional wet peak measurements. The compact design of GroPoint Pro allows users to install it quickly with minimal soil disturbance. When installed vertically, GroPoint Pro will calculate the average volumetric moisture content within a 15cm soil layer; When installed horizontally, the sensor can be used to measure the soil moisture content at a certain depth.

GroPoint ProIt can be placed in irrigation sensitive areas, such as around the rhizosphere. During the irrigation process, when the water reaches the end of the sensor, irrigation can be stopped after obtaining the optimal irrigation amount, ensuring only the required irrigation amount is applied to achieve sufficient control over precise irrigation.

TensioMarkMeasure soil water potential or substrate potential. The potential of soil matrix is the pressure required to remove water from the soil, which is a pressure indicator for plants and crops and can be used to determine soil water flux and available water in the soil. The ceramic tip of the sensor for measuring heat capacity is balanced with water. Then, based on sensor specific calibration, the substrate potential is calculated according to the thermal storage characteristics of the soil.

due toTensioMarkThe measurement is based on the thermal properties of the soil, so it does not require user calibration, does not require water filling, has excellent accuracy and stability, and has a larger range than any conventional tensiometer.
