Inline Single-Kernel Moisture Monitoring — Rice, Paddy, and Wheat
Measure grain moisture continuously as it moves through your facility. The RX20 installs directly in the grain flow and reads single kernels in real time, giving millers and elevators live moisture data without pulling samples. A touch-panel controller, multi-sensor support, and data logging turn moisture readings into process control.

The RX20 brings continuous moisture measurement into the grain flow. Its single-kernel sensor installs inline, inside an elevator or bucket, and measures moisture as grain passes through. Instead of stopping to pull samples, operators see live moisture on a touch-panel controller and can act the moment readings drift. The system scales from a single measurement point to a full facility network.
The RX20 uses a Kett single-kernel electrical resistance sensor with calibration curves developed by Kett for rice, paddy, and wheat. 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.
Need to measure corn or soybean as well? The RX30 Inline Grain Moisture Meter adds large-grain coverage to the same inline system.
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.
