ENVIROSMART Water Movement Systems

The EnviroSMART TM probes are manufactured by Sentek to provide soil water content profiles for irrigation scheduling or other water movement systems. The measurement range is oven dry to saturation. The probes measure soil moisture at multiple depths and are easy to install. Tools offered by Campbell Scientific allow the probes to be installed with minimal soil disturbance.
EnviroSMART is recommended for higher accuracy research measurements, measurements deeper than 80 cm, or stony soils. It is customized for individual applications by adding sensors at user-specified measurement depths. The maximum measurement depth of the standard configuration is 6 feet (2 m); deeper measurements are possible with special provisions.
