GroPoint Profile provides cost-effective measurement of volumetric water content over multiple depths using a single probe, eliminating the cumbersome excavation required for multiple sensors placed at different depths.


It can be deployed in irrigation-sensitive zones to enable full control of precision irrigation needs, providing an understanding of water movement through the soil.

The sleek, lightweight design installs quickly with minimal soil disruption using a pilot rod and slide hammer tool. Designed for vertical installation, the sensor takes measurements over multiple soil layers, with each measurement zone (segment) providing the average volumetric soil moisture content over a 15 cm range (approximately 6 inches).



The Most Accurate and Cost-Effective Soil Profiling Solution Available

  • Eliminates need for multiple sensors and cabling systems.
  • Installs quickly and easily without excavating.
  • One SDI-12 address is used to read all segments, providing for simplified installations. Optional RS-485 output.
  • Moisture readings can be user-calibrated with 3rd-order polynomials to meet custom requirements.
  • Low power requirements—suitable for remote, autonomous applications.
  • Patented TDT5 technology for scientific-grade accuracy and excellent long-term stability of measurements.
  • Fully potted electronics for excellent durability.
