Larger Volume of Influence
Use the 10HS to accurately measure water content where a large volume of influence is needed, with minimal salinity and textural effects in most soils.
Characterize Spatial Variability
The 10 cm long 10HS has a ~1.3 liter area of influence. Reference our Application Note to see the idealized measurement volume of the 10HS.
Engineered for Accuracy
The 10HS determines volumetric water content (VWC) by measuring the dielectric constant of the soil using capacitance/frequency domain technology. Using a 70 MHz frequency minimizes salinity and textural effects, making the 10HS accurate in most soils. Factory calibrations can be used in most typical soils with a saturation extract EC of 10 dS/m.
The 10HS’s analog signal means no-hassle integration with systems manufactured by other companies. An on-board voltage regulator allows 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 conversion equations.
