Soil moisture sensor SDI-12 Standard, with patented technology to measure the two most significant soil parameters: moisture and temperature. Available with cable in varying lengths for fixed installation.
Looking for a rugged soil moisture sensor for long term monitoring? The HydraProbe SDI-12 Standard soil moisture sensor is suitable for the measurement of soil moisture in all soils. It can measure moisture in the range from completely dry to fully saturated, with an accuracy of accuracy +/- 0.01 WFV.
The HydraProbe is the most scientifically researched soil sensor available and is depended on by the USDA, NOAA, farmers, leading irrigation companies, and universities for over 25 years. It has been engineered to handle the terrain you want to measure and provides data you can trust year after year.
The temperature range is -10°C to 60°C, with a measurement accuracy of 0.3°C. The information can be read out with a data logger.
If you want to measure soil moisture and temperature only, the HydraProbe Standard will suffice. If you want to measure salinity as well, choose the HydraProbe Pro.
The following variations in cable length are available:
To get immediate readings of the current measurement conditions from your HydraProbe sensor, you can opt for the complete set with read-out unit. The handheld read-out unit reads data from HydraProbes and displays the volumetric moisture content as a percentage. It features a large display window in a robust weather resistant casing.
