10HS Soil Moisture Sensor

Better averaging means better data

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 TEROS 12 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.

Sublimely simple

Push the 10HS directly into undisturbed soil, plug it in, and start collecting data. It's that easy with METER's ZL6 Data-logger data logging system.

A sensor that adapts to your needs

The 10HS's analog signal means no-hassle integration with systems manufactured by other companies.

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.
