GroPoint Pro

Moisture, salinity (electrical conductivity), temperature and wetting front in a single SDI-12 sensor.

The GroPoint Pro soil sensor is robust, reliable and highly accurate, providing cost-effective measurement of soil moisture, soil temperature, salinity (electrical conductivity or EC).

This SDI-12 sensor also functions as a wetting front detector, providing a separate output for the wetting front measurement. By placing the tip of the sensor just above the bottom of your crop's root zone, the wetting front measurement will indicate when water has reached the bottom of the probe during irrigation, allowing you to have your irrigation stop at precisely the optimal time to ensure only the water needed is applied.

The sleek, lightweight design installs quickly with minimal soil disruption. When installed vertically, the sensor averages volumetric moisture content over a soil layer of about 6” (15cm). When installed horizontally, the sensor can be used to measure moisture at a specific soil depth.
