The Terrasonde dielectric soil moisture probe was developed in 2013 by HUSSAT. The Terrasonde translates over 60 years of combined field and specialist technical knowledge into a purpose built, affordable, dielectric sensor for agriculture.
Features
-
Available in lengths of 120cm and 180cm with 4, 8, 12 or 16 sensors placed at intervals of 10 or 20cm.
-
Built-in underground telemetry with lithium battery that allows daily measurements in dryland applications to be sent to the internet for up to 10 years without requiring battery replacement.
-
Leading edge RF circuit design, mathematical model and factory calibration procedure that allows Terrasonde to accurately measure the complex dielectric permittivity of the soil.
-
Incorporates published relationships between dielectric permittivity and soil water content to reliably estimate soil water content.
