Inline Single-Kernel Moisture Monitoring — Corn, Soybean, and Grain
Measure moisture continuously as grain moves through your facility. The RX30 installs directly in the grain flow and reads single kernels in real time, covering large grains like corn and soybean alongside barley, wheat, and rice. A touch-panel controller, multi-sensor support, and data logging turn moisture readings into process control.

The RX30 brings continuous moisture measurement into the grain flow for facilities handling large grains. Its single-kernel sensor installs inline, inside an elevator or bucket, and measures moisture as grain passes through, covering corn and soybean as well as barley, wheat, and rice. Operators see live moisture on a touch-panel controller and can act the moment readings drift, with no need to stop and pull samples. The system scales from a single measurement point to a full facility network.
The RX30 uses a Kett single-kernel electrical resistance sensor designed for larger grains, with calibration curves developed by Kett for corn, soybean, and a full range of cereal and rice grains. Readings flow to a touch-panel controller and to PC software that consolidates data across every connected sensor, generates PDF reports, and integrates with external databases. Cable runs reach up to 500 meters, so sensors can sit where the grain is while the controller stays accessible. Optional cloud storage adds remote monitoring and long-term comparison. The system includes five years of data updates and is backed by the One Year Kett Total Care Warranty, covering parts, labor, and specification compliance.
Measuring only rice, paddy, or wheat? The RX20 Inline Grain Moisture Meter offers the same inline system tuned for smaller grains.
Need a simpler single-point monitor without PC integration? The PT2700 Inline Grain Moisture Monitor mounts on a dryer and reads moisture on its own display, no computer required.
