Description

The HydraLINK™ probe is the latest in the soil moisture probe range from Hydra Sensor Technologies International Ltd and uses capacitance as the measuring technology. The HydraLINK™ probe is supported by its own Telemetry. The HydraLINK ™ probe can be deployed on any irrigation systems whether its center pivots, drip irrigation, micro irrigation and is suited for surface and flood irrigation. The probe comes with 5 sensors and can be upgraded to 10.

Monitoring crops allows for water savings in the range from 69% to 92%, compared to non-monitored crops. Using probes, farmers know the right time and the amount of water needed for optimal plant growth.
