Soil is a naturally heterogeneous system, which means small soil moisture sensors may not provide good enough answers to your soil moisture questions. The larger 10HS soil moisture sensor is better at averaging varying soil moisture and characterizing spatial variability because it averages soil moisture over a greater volume.
The 10cm long 10HS has three times the volume of influence compared to smaller sensors, measuring one liter of soil volume. Most soil sensors that measure this much volume are 20cm or longer, causing installation headaches. The 10HS provides the perfect balance between volume of influence and sensor size, installing easily into the sidewall of a narrow trench.
The 10HS measures volumetric water content by means of FDR technique. The high frequency of measurement minimizes salinity effects and textural effects, making this sensor accurate in a large range of mineral soils. For soilless media, we recommend the TEROS12 sensor.
A special coating makes the 10HS soil moisture sensor resistant to salts. Very low power consumption and a high resolution provide increased precision over a longer period of time.
Push the 10HS directly into undisturbed soil, plug it in, and start collecting data by using the appropriate registration system.
The 10HS’s analog signal means no-hassle integration with systems manufactured by other companies.
Soil is highly variable in space. The 10HS soil moisture probe with its larger volume of influence can smooth variability and accurately characterize highly heterogeneous soil water content. It’s the perfect balance between volume of influence, accuracy, affordability, and ease of installation.
