GroPoint Soil Moisture Profile
RioT GroPoint soil moisture sensors provide accurate, long-term monitoring of soil moisture and temperature for agricultural, environmental, hydrological, and research applications. Using patented TDT⁵ (Time Domain Transmission) technology, GroPoint sensors deliver reliable volumetric water content measurements with minimal calibration requirements across a wide range of soil types.
Designed for permanent field installation, the GroPoint profile sensors to support irrigation management, environmental monitoring, and scientific research.
Accurate Soil Monitoring
GroPoint sensors provide continuous measurement of:
Volumetric soil moisture profile
Soil temperature
Their advanced TDT⁵ technology delivers high accuracy while remaining largely unaffected by soil texture and moderate salinity, making them suitable for a wide range of field conditions.
Typical Applications
GroPoint sensors are widely used for:
Irrigation scheduling
Agriculture and horticulture
Environmental monitoring
Hydrology and catchment studies
Turf management
Scientific research
