If your soil is extremely heterogeneous, 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 best volume of influence to sensor size on the market
The 10 cm long 10HS has three times the volume of influence compared to smaller sensors, measuring 1 liter of soil volume. Most soil sensors that measure this much volume are 20 cm 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.
Fast, accurate water content measurements
The 10HS measures volumetric water content by means of capacitance technology. Its high measurement frequency minimizes salinity and textural effects, making this sensor accurate in a large range of mineral soils. Factory calibrations can be used in most typical soils with a saturation extract EC of 8 dS/m or less. (For soilless media, we recommend the GS3 sensor.)
Get more for less
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.
Get the perfect balance
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.
