10HS Soil Moisture Sensor

Larger Volume of Influence

Looking for a soil moisture sensor with a greater volume of influence? Use the 10HS to precisely analyse water content where a large volume of influence is required, with minimal salinity and textural effects in most soils.

Characterize Spatial Variability

At 10 cm long, the 10HS has a 1 liter area of influence. Picture the probe running the length of a one liter bottle – the bottle represents the approximate area of influence. The 10HS predicts the volumetric water content of the soil within that area.

Engineered for Accuracy

The 10HS calculates volumetric water content (VWC) by analysing the dielectric constant of the soil using capacitance/frequency domain technology. Using a 70 MHz frequency minimizes salinity and textural influences, making the 10HS accurate in most soil types. Factory calibrations may be used in most standard soils with a saturation extract EC of 10 dS/m.

Integrate with CSI Data Loggers

The 10HS’s analog signal means simple integration with other companies’ systems (such as Campbell Scientific). A built in voltage regulator permits the Decagon factory calibrations to be used with any excitation voltage between 3 and 15 V.

Use with the Topp Equation

The 10HS’s output can be set to dielectric for use with the Topp Equation or other dielectric-to-volumetric water content conversions.

Reasons to pick the 10HS:

• If volumetric water content is the only measurement you need.
• If you just want a simple, all-purpose sensor with excellent accuracy.
• If you are interested in a large volume of influence.
