Overview

The EnviroSCAN probe provides 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. EnviroSCAN is recommended for higher accuracy research measurements, measurements deeper than 80 cm, or stony soils. It is customizable by adding sensors at user-specified depths.
