GroPoint - by RioT Technology Corp. products

The Only Soil Moisture and Temperature Profile Sensor To Give A True Soil Moisture Profile. Continuous soil moisture measurements over the entire length of the probe. Configurable with or without soil temperature measurements at every 10 cm. Available in 6 different probe lengths. SDI-12 interface, optional Modbus over RS-485. Based on our unique patented TDT5 technology. Comes with 3 m (9.8`) durable cable (Flying lead Standard, Optional 5-pin IP68-rated M-12 or 4-pin IP68-rated EN3 connector available). Factory-calibrated for most agricultural soils, but can be custom calibrated before shipping—request when ordering. Soil sensor can be custom calibrated by the customer—see the detailed procedure in the User Manual.

The GroPoint™ Lite is robust, reliable and highly accurate, providing cost-effective soil moisture and soil temperature measurements. The sleek, lightweight design installs quickly with minimal soil disruption. When installed vertically, the soil moisture sensor averages the volumetric water content over a soil layer of about 6” (15cm). When installed horizontally, the sensor can be used to measure soil moisture at a specific depth. GroPoint Lite can be deployed in irrigation-sensitive zones, such as around the root zone, to enable an irrigation monitoring system and increase water-use efficiency.

The GroPoint™ Pro soil sensor is robust, reliable and highly accurate. It provides a cost-effective solution for measuring soil moisture, soil temperature, and salinity (electrical conductivity or EC). This SDI-12 soil moisture sensor also functions as a wetting front detector, providing a separate output for the wetting front measurement. By placing the tip of the soil sensor just above the bottom of the crop’s root zone, the wetting front sensor will indicate when the water has reached the bottom of the soil sensor. This allows irrigation to stop precisely at the right time to ensure only the water needed is applied.

GroPoint™ Classic is our original analog soil moisture sensor, with a rugged design that has been proven over decades of use. The sensing element is manufactured from a solid 7mm (0.28″) stainless steel rod, and all electronics are sealed in water-proof epoxy. The 4-20mA output integrates easily with common irrigation control and management systems, and it’s also available with 0-5mA output. The standard 5m cable can be extended to up to 150m (500′) and terminates in a rugged IP66/68 environmental connector or bare wires.
