CS620 Water Content Sensor

Overview

The CS620 is the sensor used in retired HydroSense system. The Hydrosense system combines a compact, handheld display and a sophisticated soil-water sensing probe in a portable package to provide quick and reliable soil-water content measurements. Each measurement takes less than one second and is obtained by inserting the probe rods into the soil and pressing a single button on the display unit. A choice of 12- or 20-cm probe rods makes HydroSense a versatile tool for monitoring and managing soil water in a wide range of conditions.
