Hydrosense Portable Soil Moisture System


The HydroSense System combines a compact, handheld display and a sophisticated soil water sensing probe in a portable package, providing you with quick and reliable soil moisture measurements in the field. Measurements are easily obtained by inserting the probe rods into the soil and pressing a single button on the display unit.

For added flexibility the Hydrosense has two modes - Water Content mode, which takes simple soil moisture measurements against standard calibrations or Water Deficit mode, which allows users to set their own parameters for up to 5 sites.

A choice of 12 or 20 cm long probe rods makes the HydroSense a versatile tool for monitoring and managing soil moisture in a wide range of applications and conditions.

  • Compact, portable easy to use soil moisture system
  • Instant measurements
  • 12 cm or 20 cm probe option
  • 2 line LCD with simple 2 button keypad
